Question

Determine two coterminal angles (one positive and one negative) for each angle. Give your answers in degrees. (Enter your answers as a comma-separated list.)

(a)    135°

 

 °

(b)    −225°

 

 °

Answer 1

To find coterminal angles you either add or subtract 360°

(a) 135+360 = 495°

135-360 = -225°

(b) -225+360 = 135°

-225-360 = -585°
