Math question (easy trig)
Posted on 2/28/21 at 7:09 am

I never took trig though so I’m clueless. I’m sure it’s some simple equation. I’ll try to explain with out a picture, it should be simple.
So we have a right triangle, but the other angles are not even. I know the hypotenuse length. I know the inner angles of the triangle , happens to be 27, 90, 63.
So I have my one single length measurement, and the angles. I want to find the other two measurements of the triangle without having to build it first and measure.
Thanks!

It's early for me but I'll say if it's a Rt triangle, the other angles MUST be 45 degrees... So something be rong with the problem from the get.
Ok, I already take that back...

sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent or sin/cos
Look up the trig functions for the angles and plug them and the length of the hypotenuse into the formulas and you'll get the other two sides.

Sohcahtoa.
Sin(small angle) = small side/ hypotenuse
Sin(small angle) = small side/ hypotenuse

Sin(27) is 0.9563
0.9563=b/hypotenuse
If i remember correctly that should give you length of shorter leg.
A squared + B squared = C squared after that, you know b and c

Do your own homework Johney

Just here to say that I hate this type of math.

What’s the hypotenuse length that you have?
Posted on 2/28/21 at 7:35 am to BigEdLSU
L *
* H * If you know the length of the hypot (L), take the Tan of
A 90 your angle (A). That will give you the length of side H.
The 90 is the location of your 90 degree angle.
Hope my attempt at diagramming is not too confusing.

Double post
But I’m figuring something much more complex than this fwiw, and I think I have the other part down, but I need these other lengths to plug into the formula I have for the other stuff.
I appreciate you guys, certainly not homework, more a gigantic time saver, much appreciated
