Convert each angle from radians to degrees: -7(pi)/3

Question

basic concept 

Answer 1

Gabrielle,

 

Two good rules to remember:

 

(1) If you are given an angle in radians, multiply by 180/π to convert it to degrees.

 

(2) If you are given an angle in degrees, multiply by π/180 to convert it to radians.

Answer 2

7∏/3 (180/∏) = 420º
