Well, take heart because the angle of depression and the angle of elevation are congruent, so even when you feel like you're looking down, you're also the person looking up to a bright future : )
I used to get totally confused to work out the angle of depression and evaluation but now from your video I get to understand and I want more of your video. Thanks
my teacher didn't even mention the fact that you have to keep the angle of depression outside of the original triangle. tysm I finally understand this topic
Really easy and straight forward, this video helped me to visualize the idea of what is really meant by the Angles of Elevation and Depression, that horizontal line was so much important.
Also sorry i have a test tommorow but im note understanding how the 10,000ft away at the end is on the sideways line inside of the ground? wouldnt it be if you. OH Shoot as im typing this im thinking and now i understand. Its because the little stick dude is all the way in a air ballon. not on the ground
i think you are mistaken with the last question, yes rounded off the answer is 5,7 but the ratio is tan not sine, the distance from the hot air balloon to the house is the horizontal length not the diagonal length.
Hi- thanks for watching and for the comment. This does sometimes trip students up at first, as they want to measure the distance along the ground. However, the distance from the hot air balloon to the house is the length of a line segment connecting those two points (the balloon and the house). If you were to draw that line on the picture it would go through the air, not along the ground. The distance you're thinking of (along the ground) is the distance from a point on the ground directly under the balloon to the house. Does that make sense?
@@RealMikeDobbs thanks for the response, but so what if its not at the same elevation as the hot air balloon, its still a distance, lets say this was on a cartesian plane, the x values from house to balloon should be the distance, however high the balloon is... shouldn't matter
I understand what you're saying, it sounds to me like you are confusing the "horizontal distance" with the actual distance from the house to the hot air balloon. If it were as you say, then no matter how high the balloon goes the "distance to the house from the balloon" would stay the same. This is of course, not true. I made a short little animation for you (on a Cartesian plane). Take a look at it. The red line is the distance from the balloon to the house. The blue line is the "horizontal distance" from the balloon to the house. The only time those two distances are ever the same is when they are at the same vertical position on the plane. Does this help? ua-cam.com/video/ojvfmUskfdE/v-deo.html
That's a common mistake. If you rewatch the first two minutes of the video, you will see that the angle of elevation and the angle of depression are alternate interior angles to each other, and therefore always the same measure. The key is that they are both measured from horizontal. Hope that helps 😄
That's just plugging into the calculator and using the Tangent function. If you aren't sure how to do that, you may want to check out my trig introduction video: ua-cam.com/video/oOoWgEcyYqs/v-deo.html
One paper this works since angle and one length is given but in real life, if given the hyponuese, angles becomes useless. Climbing a tree is easier than using a tiny protractor on meters long paper to measure angle.
Hey, thanks for watching and commenting 😀 I’m not sure I follow exactly what you’re saying. In practice it’s much easier to measure angles in real life than it is to measure distances. I suppose it all depends on what you’re trying to do. These days if you wanted to know how tall something is you could just send up a drone with an altimeter- but if you go back 40 years or so, it would be much easier and more practical to measure a distance away from the tree on the ground and then measure the angle of elevation and use some trig. That’s more or less how all maps were created before we had GPS. Surveyors would pace or measure out distances along the ground, and then measure angles between points to calculate other distances. Climbing tall objects also introduces many risks that walking on the ground does not. It’s also worth noting these are sanitized examples designed to allow HS students to practice basic skills and don’t accurately represent the many additional complications you would encounter in the real world. For example, over long enough distances you need to start taking the curvature of the earth into account depending on how accurate you need your eventual calculations to be.
That's fair 🤣 I'm better at math than at drawing, but as I always tell my students: it doesn't matter if your picture is good, it only matters if it's useful.
Easy fix- you’re in Radian (Rad) mode. Radians are a different way to measure angles. You need to change your calculator to degree mode when working in degrees.
he is really good at this but I had a problem with him talk to fast for me to even calculate for myself and try to see if I understand and maybe u should maybe give us a minute to try and answer the question
Thanks for watching 😀 I’m sorry you felt the pace was too fast. Since everyone works at a different pace- what I try to do is keep the video moving with the understanding that you can pause at any time. When working through the problems in a video I would recommend you pause it after the problem has been presented. Try to set it up yourself, then play forward and see if you set it up the way I did. Then, pause again before I work out the Algebra and do your own Algebra. Then play to see if we arrived at the same result. Otherwise the videos become too long and I feel a lot of people won’t watch an hour long video on a topic.
@@RealMikeDobbs Now I understand why u fast but u really good at this and I learn't a lot on the video and want to thaank u for making me understand the concepts
That’s nice of you to say. I always say, “Experience looks a lot like intelligence, and you can get all you want.” You’re watching me in an area which I have deep experience over a log period of time. I hope it helped you out 😀
Tomorrow I have a math exam, and I was so stressed, but after watching your videos, I understood everything. All the love from Saudi Arabia

the angles of depression gave me depression so im the person sitting at the top of a building lol
