Simple answer to the equation without the circumstances:
3.1x - 1.6x = 35 + 10
1.5x = 45
x = 30
Both angles have to be 90 so if you find the value for x for one you get the other one ahmatically answer is 22 btw :)

Step-by-step explanation:
Answer:
f(x) = + cosx or - cosx
Step-by-step explanation:
(2+tan^2x/sec^2x) -1 =(f(x))^2
=(( 1 + sec^2x)/sec^2x) -1
= 1 / sec^2x + 1 - 1
= 1 / sec^2x
= cos^2x
(f(x))^2 = cos^2x
f(x) = + cosx or - cosx
