Make sure you set your calculator to degrees rather than radians before doing this problem. On a TI 84-84plus degrees vs radians can be found under "mode".
hii- I don't normally comment on yt vids, but i just wanted to thank you for this as i have my exam tomorrow and couldnt find any other resources available to explain this concept to me- TYSM FOR SAVING MY GRADE
Respected Sir! You have done questions which no one mentions properly because they are difficult to solve but you have made them super easy.Thank you so much sir.Please make some more videos every week.I need your help as I teach O level students and I want to take concepts and then share with my students.
So the example at the beginning, what the hell used and the two friends was used to demonstrate Angle of elevation's and angle of depression simultaneously with a backwards Z! this man is a lifesaver!
Thanks a ton, i was a non math student from high school to Graduation, but for my post grad. In MBA, here in India, we've to prepare for CAT exam for which we need to recall as well as ace all the Quant related topics. This video helped me clearing a lot of doubts. M looking forward to watch more of this channel's videos. Thank you for such informative and elaborative video. 🇮🇳
1. A boy 1.8m tall standing 20m away from foot of a palm tree observes the angle of elevation of top of palm tree as 45° A. Find the height of the palm tree B. Find the angle of elevation of the top of the palm tree from the foot of the boy. 2. Two points P and Q 15m apart are on one side of light house, if the angle of elevation of the top of the light house from P and Q are 30° and 60° respectively. A. Find how far Q is,away from the foot of the light house. B. What is the height of the house? 3. A boy observes that the angle of elevation of the top of the tower as 32°. He then walks 8m towards the tower and then discovers that the angles of elevation of the tower is 43°. Find the height of the tower. 4. A ladder 23m long leans against a vertical wall which makes an angle 68° with the horizontal. A. How high up the wall is the ladder B. If the height of the ladder up the wall is reduced by 4m,by simply shifting the foot of the ladder backwards, find the vertical angle of the ladder
thankyou, this was extremely helpful. i entered a new school and therefore a new math class in which they handed me a sheet i had to do with angles of elevation and depression but i hadnt been taught it at my previous school so i had to learn this new concept and your video was by far the best id found on the topic
Bruh I’m gonna be real here,this video saved my geometry grade,I actually got a correct answer using this video on a similar problem and I cried no joke
I was having issues grasping one thing in this topic, and it kept messing me up on graded assignments etc, so thank you for the helpful video. It's much appreciated. :)
Hello, I'm confused about the angle of depression drawn from the top of Building A when the question stated "the angle of depression from the base of of Building B is 34 degrees;" I thought that the shape will be in the form of a parallelogram. What did I miss please?
why cant i - for the second question - subtract the 3 angles we have already from 180 to end up with a angle of elevation from the bottom of building A to the top of building B ? which would = 66 degrees and then we still use the 35 base? this gets us 78.61... i know its wrong but why ? it feels as tho it should work
why wouldn't u measure from the angle of depression of the person on the cliff and use the Sin function? isnt that the angle we are originally taking the measurement from?
I know I'm not trippin', when he is solving for (Tan) why is he doing 35 divided by tan56 to get "a" when really to solve for "a" it is the opposite and one would actually have to multiply Tan56 and 35 to solve for "a" . He is confusing me I'm going to look for another video to confirm.
In both the first and second example, How did you get the final answer in the final solutions. I mean looking at the last example the tan of 56 degrees being 23.6m you just jumped and got that answer.
Jonathan Mckeon if u want to solve it manually or without the help of the calculator, i hope you like multiplying huge and loooooong chunks of Decimals...
It'll be a lot easier to understand if you used a guide like SOHCAHTOA. This video really helped me with the word problems and such. Thank you for posting this, sir.
Please I need someone to help me solve these angles of elevation. 1. From two points x and y 8m apart and a line with a foot of a hill. The angle of elevation of the top of the hill is 30 degrees and 60 degrees respectively. Find a hill of hill above the ground. 2. A boy noticed that the angle of Revelation of a 60 m vertical pole is 50 degrees. He walks Xm towards the pole and observes that the angle of Revelation has increased by 15 degrees. Find X. 3. A plot to fly an airplane at a certain constant high reported the angle of depression of a lake at 28 degrees after flying 30km in the direction of the lake. The angle of depression became 42 degrees. Find the high of the aeroplane. 4. The angle of evelation on the top of a house from a button of a tower 160m high is 26 degree from the top of the tower the angle of elevation is 24 degree what is the high of the house if the tower and the house are 50 m apart. 5. A flag pole and a building stand on the same horizontal level from the point P at the button of the building the angle of elevation of the top of the flag pole is 65 degree from the top Q of the building the angle of the evelation of the point 25 degrees if the building is 20m high calculate the (i) Distance PT (ii) high of the flag pole (iii) Distance QT
An angle of elevation of the top of a building from a point P is 45.From a point Q,which is 10m from P towards the base of the building,the angle of elevation is 48.calculate the height of the building
I don't understand how you got 15.6 for c... I put it in the calculator as 35/tan24 degrees on several different calculators and it kept coming up as 78.6112870882. Can you explain what it is you did exactly to get 15.6=c please....
Triangle and is an equilateral triangle of side lenght x cm....angles ADB and DBE are right angled...find the side of and ABC EQUILATERAL TRIANGLE ..wen BE Is 16 cm and DE is 20 cm...pls help
because the angle is supplementary, which means its a right angle. Right angles are always 90 degrees. You know its supplementary because the horizontal lines that make up the angles of depression and elevation are always parallel.
Math is making me go down the angle of depression ☠

You teach better than my young teacher, she 26 and only talks wit students and barely teaches good
where the hell did he get 56 degrees from someone please tell me im so confussed??
He got it from 90 degrees minus 34 degrees.
90 - 34 = 56
A right angle is 90 degrees.
oh ok thanks so much
@Restock GT because it is right triangle.
I used tan34*=a/35 and it worked fine. I got a=23.6m as my answer too and 39.2 for the height of building B :) thank you so much
how did he get the 56 degree please help thank you
how is the bottom angle 56? just need to know so I can interpret by myself

Hello,

Thanks this helped a lot clearing my doubt 🙏
Some(sin) people (perpendicular) have(hypotenuse) curly (cos) brown(base) hair(hypotenuse) through (tan) proper (perpendicular) brushing (base)
man, you just made everything clear to me, thanks a lot fam
I learned more from this video than a week of Trig class :/
thank you soooooo much. You are way more clear than my teacher is.
How come did you get that 78 when 60m-12=48 ?? Im so confused tho
GOD bless you all 🙏💜💜
why cant i - for the second question - subtract the 3 angles we have already from 180 to end up with a angle of elevation from the bottom of building A to the top of building B ? which would = 66 degrees and then we still use the 35 base? this gets us 78.61... i know its wrong but why ? it feels as tho it should work
why wouldn't u measure from the angle of depression of the person on the cliff and use the Sin function? isnt that the angle we are originally taking the measurement from?
how are you supposed to solve for "a" in the second example tho?
Oh wrong video,
I was looking for depression problems
Good video. It would be a great help if you showed the algebra work also.
ummm you did it wrong it is supposed to be opposite over adjacent so it is x/60
That would be the tangent of 78° which would also work.
umm no. if you refer to 78, the opposite side’ll be the x and the adjacent side’ll be the 60 m. but since we referred to 12, it’s the vice versa. 😂
I know I'm not trippin', when he is solving for (Tan) why is he doing 35 divided by tan56 to get "a" when really to solve for "a" it is the opposite and one would actually have to multiply Tan56 and 35 to solve for "a" . He is confusing me I'm going to look for another video to confirm.
Exactly correct. I'm confused because I thought he should have multiplied it.
Wonderfully explained. Thank you :)
Ok
you're welcome !
1st comment here---------->thanks dude helped alot
I have a quiz but I mostly forgot all of these stuff from geometry! Thank you sir it is very helpful.
Thanks I'm in year 6 and I have S.A.T.S. in May and we needed this

How did you even get that 282?? Asking only im so confused about your calcylatingbthings 😭
In both the first and second example, How did you get the final answer in the final solutions.
I mean looking at the last example the tan of 56 degrees being 23.6m you just jumped and got that answer.
he substitute it and did 35÷tan56=23.6 I was also saying the same thing as well
Thanks dave but do you have to you the caculator on this? I mean s there a way to solve the Tan,cos and sin without the calculator?
+Jonathan Mckeon I normally use the calculator, some calculator you have to press the tan sign first then enter the number you want the tangent of.
Jonathan Mckeon he used a calculator, because the values of sin, tan, and cos is a rly long decimal.. u need a calculator to solve it
Jonathan Mckeon if u want to solve it manually or without the help of the calculator, i hope you like multiplying huge and loooooong chunks of Decimals...
just remember SOH CAH TOA. Sin= opposite over hypotenuse, Cos= adjacent Hypotenuse, Tan= opposite over adjacent

Helped a lot wish you'll still make a lot of videos,
Wow this dude taught me math better than my actual math teacher
Why didnt you make horizantal line at the eyes'of the observer while you made at his legs or tip of the cliff
From.somaliland.
i'm so confused on how he got 56 for the height on the second one, this is probably a dumb question but i don't understand
Where did you get 56 degrees from 10:22
How would you find the distance between the 2 angle
Thanks for the video nothing in class made sense until you described it
Is it possible to have a condition when angle of elevation and angle of depression are not equal?
I would like to know about the tan part when I do that part it's wrong
this helped me so much
You made a mistake at the second triangle. Because Tan has to be Tan 24= 35/C so the C side is 78m
I don't understand how you got 15.6 for c... I put it in the calculator as 35/tan24 degrees on several different calculators and it kept coming up as 78.6112870882. Can you explain what it is you did exactly to get 15.6=c please....
Teacora Sherrill you have to do 35tan(24), not 35/tan(24)
Please if you could send an easier Video. It would be great
Thank you 🥺
Thank you so much bro I studied so much and I couldn't get angles of depression but after this vid I completely get it

how did you get 23.6 in building a?
This is so helpful. Thank You So Much...!!!!!
5:55 how did he get 90 from because he subtract 90 by 12 and got 78 but where did he get the 90 from
because the angle is supplementary, which means its a right angle. Right angles are always 90 degrees. You know its supplementary because the horizontal lines that make up the angles of depression and elevation are always parallel.
I dont know how to do the approximately thing on the calculator it keeps giving me errors
