Answer:
radians = 7π/3 ...... or ( π/3 ) ... First quadrant
Step-by-step 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
