Question

Find the missing SIDE "X".

Answer 1

Ughh trig
I think what you gotta do here is use tangent because you are dealing with opposite and adjacent. Doing tan(41) will give you x/10. tan(41) is 0.8692... and you can just multiply that by 10 because x is being divided by 10, so x is around 8.69.
Now, with the two legs, you can use Pythagorean theorem to find the hypotenuse.
You already have 2 angles (right angle and the angle we just used to find x) so we can use the fact that all triangle angles add up to 180 to do 180-90-41.

In the end, x ends up being around 8.7, the hypotenuse around 13.3 and the last angle 49 degrees.
