Finding Coterminal Angles In Exercises 29 and 30, determine two coterminal angles (one positive and one negative) for each angle. Give your answers in degrees. 45 degree -36 degree 120 degree -420 degree

Solution

29) Coterminal angles can found by adding and subtracting 2pi or 360 degrees to the original angle.

so 45 degree is itself it\'s coterminal angle. and other two coterminal angles are:

45+360=405 degree

45-360= -315 degree
