Answer 14

Remember 360° represents a full rotation around the circle.
i.e. position of 502 is the same as the position of 502-360=142°

Answer 15

Also 502° is positive so we go against the movement of a clock.

Would this be it @math&ing001

Answer 17

Nope that's going clockwise.
When the angle is positive we go counterclockwise.
