Answer:
The reference angle is 60°
Step-by-step explanation:
Given the angle 120°
we have to find the reference angle of 120°
The reference angle is always the smallest angle made from the terminal side of an angle with the x-axis.
Angle 120° lies in second quadrant
To find the reference angle measuring x° for angle in Quadrant II, the formula is (180−x)°
Reference angle=(180-120)°=60°
hence, the reference angle is 60°
