Trig Question!!!!!!!!!!!!!!!?

A co-terminal angle is an angle that is exactly 360 degrees, or 2 pi, away from an angle. So to find the co-terminal angle of A), add 2 pi, or in this case 36 pi/18, and subtract that same value to get your two answers. Do the same thing with B) except add and subtract 360 degrees then put your answer in the desired form. Hope this helped :)
