Find the degree measures of the radians given.

Question

1. pi/15 rad

= 12 degs

2. -9pi/2

= -810 degs

3. 5pi/3

= 300 degs

4. -3pi/4

= -135 degs

5. pi/10

= 18 degs

6. -11pi/15

= -132 degs

7. In which quadrant is -11pi/9?

= quadrant 2

8. Find one positive and one negative coterminal angle for -410 degrees.

= -50 and 310 degs

Answer 1

Looks good to me. All you really have to do is remember that pi radians = 180 degrees.
