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.

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

Nevermind, still can’t find a rational answer

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

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)

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

[@christinekatedavid6223]

[@NESSOELR]

Thank you for this !!

[@calebho1353]

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.

[@joylynn1115]

Yeah i got nothing else to do haha

[@calebho1353]

Hehe lol

[@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?

I just wanted to say "yopposite" is how I'm going to say that world now.

[@davem45]

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.

[@ArtBellJr]

Not if you're measuring from the ground up. If you add in a line of site you would add it to Y in the equation, either way you come up with the same answer.

[@bionic909]

How do you do it? I can't find any way of doing it without a calculator

[@void_7607]

@@Tar-Illir It is impossible to take every possible value, but you can still take and compute a ton of values. You should memorize the sins and cos for 30, 45, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, and 360 degrees. For some other values like for example 18, you can use trig identities to solve for those. But yea you cant compute like sin of 2.4 or something like that.

would recommend 35/10, it has helped a lot, just one question, why do your "T's" have strange appendages sticking out of there bottoms? (also i have this sudden urge to got stare at a balloon....)

[@doright6461]

So that 30 degree is interesting is it not? Perhaps I wonder if there is a relationship on the axial turning process that dictates why 30 degrees is the best included angle for a lathe center. Hmm? Well, From my experience. A 45 degree would suggest a force environment of equal pressure from two planes effecting the tail support. As a Lathe usually goes is that there is usually more cutting force toward the axial distance of a shaft or centerline of the spindle itself. Hence, more need for radial support to control the diametric stability of the axial cut. So being that a 60 degree Included tailstock has an angle closer to the centerline it supports the longitudinal cut on a radial basis to ensure diametrical consistency. I just wonder .. should it be an included angle with all these decimals, like pi, of 30"33"33.333333 lol. I really don't care after having seen the answers on comment and actually lapping within 20 millionths and 5 microfinish. heh. I want a vacation ;- )

What if you don't know the angle. How you going to figure out the height then ?

[@fraserfrazzle690]

use pythagoras, if you have 2 sides, use them to find the square of the other then find the square root of your answer

[@richardbailey2001]

You're absolutely correct... it's nearly impossible to figure out any problem without at least two pieces of information regarding angles ....

[@imperius5765]

So here's a question. If we're capable of measuring the distance of 2000 ft. and even the angle of 30 degrees, why can't we just measure the height? I'll tell you why, trigonometry, that's why.

Nice experience

[@andyakarudolfhessiansack7936]

I really want to understand this. Where did the .577 come from? Pls help bud.

[@charlestyler9745]

+Rudolf Hessiansack .577 comes from the angle: If you go 100 feet, and there is a 10 feet more elevation, there is a certain angle to this. 45° means that the height is the same as the distance you are away from the object. tangent 45° (tan) shows this.

[@louisphilippe1100]

Make sure your calc is in degree. Put Tan(30) and you get .577. Multiply that by the length (2000) and you get 1154.700538. Put Round(1154.700538 ,2) and you get 1154.7

I have an important question. It involves trigonometry but obviously I haven’t taken a course. I want to know the height of an object but I don’t exactly have the distance from one point to underneath the object. What I DO have is 3 locations, the coordinates, the distance between them.... As WELL as the angle in degrees (in altitude) that the object is from each location. How can I find the height of the object as well as it’s location in contrast to the 3 locations that I have? I know there is a way to intersect each angle and wherever the 3 lines (angles in altitude) intersect is where the object should be. But I don’t have a computer program to enter these values ...I mean if you KNOW one I can use please recommend it..but I was doing this by hand.....
