Question 966650
radians = degrees * pi / 180


degrees = radians * 180 / pi.


you have 120 degrees.


radians = 120 * pi / 180 which is equal to 120 / 180 * pi which is equal to 12/18 * pi radians which is equal to 2 / 3 * pi radians.


radians is equal to pi.


degrees = radians * 180 / pi.


degrees = pi * 180 / pi which is equal to 180 degrees.


remember those 2 formulas and you should not have any trouble converting from one to the other.
