Answer 1

radians = 7π/3 ...... or ( π/3 ) ... First quadrant

Explanation:

Find:-

What is the radian measure of an angle whose measure is −420°

Solution:-

- The radian angle for angle given in degrees = 420°. The conversion relation of angle in degrees to radians is as follows

radians = degrees*2pi / 360°

radians = 420° * 2pi / 360

radians = 7π/3 ...... or ( π/3 ) ... First quadrant
