Question

Determine the reference angle, in radians, associated with the given angle. Write the exact answer. Do not round,0=13л12

Answer 1

An angle's reference angle is the measure of the smallest, positive, acute angle formed by the terminal side of the angle and the horizontal axis.

We need to go back 13 pi/ 12 - pi

13 pi/12 - 12pi/2 = 1pi/12

The reference angle is pi/12
