Answer: Choice A) 526 degrees, -194 degrees
==============================
Work Shown:
A coterminal angle points in the same exact direction as the original angle.
Because there are 360 degrees in a circle, this means we can add 360 to the original angle to get 166+360 = 526, which is one positive coterminal angle to 166 degrees.
Subtract 360 from the original angle and we'll get a negative coterminal angle
166 - 360 = -194
Your answer will be 17/15
Firstly you should use Pythagorean’s theorem like this
H²=p²+b²
Where p is bc
And b is ac
Then keep the value and solve it and you will get h as 17
At last keep cosA = b/ h
