Find an angle between 0° and 360° that is coterminal with the given angle. −200°?

The required angle
= -200° + 360°
= 160°

Simply add or subtract 360° from any angle to find a coterminal angle. Add 360 to -200 to get the coterminal angle in the first cycle:
360-200 = 160° is coterminal with -200°

160 ⁰

360-200 = 160°
