One radian is equal to 180/pi degrees. Thus, to convert an angle from radians to degrees, multiply it by 180/pi.

Therefore, [3pi/5] radians = [3pi/5 * 180/pi] degrees = 108 degrees [pi/12] radians = [pi/12 * 180/pi] degrees = 15 degrees

[7pi/6] radians = [7pi/6 * 180/pi] degrees = 210 degrees

[5pi/4] radians = [5pi/4 * 180/pi] degrees = 225 degrees

In the problem page, it is not clear whether there is a negative sign before each value or not. In the case, there is a minus sign before each angle in radian, the same sense will prevail in degrees too.
