How is the answer pie over 2?

330 degrees = 11pie over 6

-105 degrees= -7pie over 12

Converting the angle in radians to degrees

3pie over 4 =135 degrees

pie over 2 = 90 degrees

pie over 30 = 6 degrees

-7pie over 5 =-135 degrees

I have these answers but I have no idea on how to get them..

Divide both sides by 2:

900 = p1/2 Radians.

OR

piRad/180Deg * 90Deg = 90pi/180=pi/2.

piRad/180Deg * 330Deg = 330pi/180=11pi/6
