Question

Could I find the two missing angle measures if I know some of the side lengths of a right triangle
need an example to plzz

Answer 1

if you know two side lengths of any right triangle you can always find the third.
as far as the angles are concerned since you already know 1 of 'em (90 degrees) you if you can find one more, the other angle would be its supplement.

Answer 2

yes, if you know 2 sides of the triangle. use the trigo function to find it

Answer 3

you can then use trig to find the angles after u have your side(s).

Answer 4

tanΦ = 4/3
tanθ = 3/4
