given: and

We use the identity: .

Factorize :

Substitute :

Multiply both sides by :

Now we have two equations:

...(1)
...(2)
--------------------------------------------------

add (1) and (2) , and we have:

use identity

subtract (1) and (2) , and we have:

Since and are positive, then lies in the first quadrant.

Note that

since given that , solution is
(result in radians)
convert to degrees
° (degrees)

Had your post be presented accurately, I would show/teach you, how to solve this (and similar) problem/problems.

But for the person who presents Math problem in this way, I will do NOTHING.
