Show the process of complementary functions to solve for the unknown angle, Θ
Cos Θ = sin (3Θ-14)

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.

for every positive x value, the y value must be greater than 1.

for every negative x value, the y value must be less than 1.

in your options, you can check to see that one of these two criteria is met. if neither are met, then it is not on a slope with positive line.
