Question

The reference angle for an angle whose measure is -440° is _____.
60°
80°
100°

Answer 1

Answer:

80°

Step-by-step explanation:

The reference angle is the smallest angle that the terminal side of a given angle makes with the x-axis.

An angle of -440° lies in the fourth quadrant.

For an angle θ in the fourth quadrant, the reference angle is 360° + θ.

The reference angle is

360° - 440° = 80°

Answer 2

Answer:80

Step-by-step explanation:

440-360=80
