Find an angle with a positive measure and an angle negative measure that are coterminal with each angle.

Question

1. 370 degrees
2. -3π /4
3. 5 π/2
pi sign = π

Answer 1

This is confusing, however, I think you want

angle-n*360-given where angle is less than 360
example:
1. 1*360-370=-10deg
2*360-370=350 deg

3. 2PI-5PI/2=-1/2 PI
2*2PI-5PI/2= 1/5PI
