      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 : )

    @aaayjaay4412 4 місяці тому +2

    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.

    • @RealMikeDobbs
      @RealMikeDobbs  4 місяці тому

      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?

    • @aaayjaay4412
      @aaayjaay4412 4 місяці тому

      @@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

    • @RealMikeDobbs
      @RealMikeDobbs  4 місяці тому

      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?

    why is it 53 too? Isn't the angle of depression and elevation both sum 90°?

    • @RealMikeDobbs
      @RealMikeDobbs  4 місяці тому

      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 😄

    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.

    • @RealMikeDobbs
      @RealMikeDobbs  8 місяців тому

      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.

      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.

      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.

      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 😀
