Finding the Height of an Object Using Trigonometry, Example 1

[Inbal_Feuchtwanger]

When I learned this back in school it really solidified my love for math. Good stuff.

Math class shouldn't have to be more than 3 minutes long

[rabeea]

I love how this is helpful even today! Thanks man!

[robbropyro]

Whod have guess id need this for a fireworks show. Great vid thanks

[richardalvarado-ikbr]

This is what I was looking for, because the "stick method" in these other YT videos might not work if you have limited space to walk off and the tree or other object is too tall to fit in your line of sight.

i dont' know how i can pass my trig class without you!

[amandasmith]

Thank you for posting this. It helped to finally understand WTF my Python course wanted as a formula. These courses gotta stop assuming I know theoretical math. Because I don't.

[Semnomic]

whats the correct formula if you know opp + adj and your looking for tan?

Another way to be clear - you know the distance of an object, you know its height and your looking the angle (tan)

@sloppyjoes7 left handed means you are in your right mind. (good for math).

[talialovestucker]

You know, just happen to have stuff to measure angles with while watching balloons😂😂😂😂😂

[rogerscottcathey]

Can you solve a kind of trig problem? what is the ratio of size to distance? If we take a 12x12 inch glass plate and etch a grid on it. Say one eighth inch square cells. Go to an airport and hold the plate at arms length in front of a 757 and back up til the entire jet just fits inside our view thru the plate. So the view length will be 96 eighths" or 1ft. Pace off our distance to the plane, and length of the plane as well. Do we now have a ratio whereby, with our plate held to the sky as a 757 jet passes over, we can roughly determine its altitude in feet with that ratio and handy new tool. Will the ratio will be constant?

Now think about it this way:
You are standing looking at the sunset when you see a hot air balloon and you think "why don't I find the height of the hot air balloon to the ground?"
Now you somehow know the length of you to the hot air balloon is 2000ft
and you also somehow know that the angle of the ground to you to the hot air balloon is 30 degrees
and this is when you realised you didn't pay attention in math class and now you are looking at this video to finally take away all your grievances because you now know how high the hot air balloon is to the ground.





Edit: this took like 6 minutes to type so please like.

thank you so much, I was stumped on how my angle was 125°

[jacobhatters]

Thanks man this was super helpful I will 100 present share this with people

[davem]

Wouldn’t you need to include the height of your person since the line of site wouldn’t be at the ground? Thanks for an easy explanation as well. It’s videos like these make it easy to understand and learn.

[kawaiimaster]

thank you so much, you just helped me so much on my exam!!

[moofushu]

Is there something you have to do if you had to calculate the height of something that is measured in inches instead feet?

[Nurutomo]

*The Formula is:*
*_Adjacent ⋅ Tan( Angle )_*


*Edit: Please like, I watch the entire video to get the correct formula! If you like, thank you :D*
_Edit: I use this formula for calculate the real height of the sun with object shadow. I watch YouTube video that use Trigonometry for calculate the height of the sun, but i dont know the formula. Then i watch this video, This is nice video and Thanks. By The Way... You are left-handed_

[namehere]

is it possible to use sin to calculate the height if you only know the hyp and the angle?
