Angle d has a measure between 0° and 360° and is coterminal with a –920° angle. what is the measure of angle d?

a) 155°
b) 160°
c) 165°
d) 170°

The correct option is B.

Step-by-step explanation:

All co-terminal angles are in the form of

Where n is any integer.

The coterminal angle is –920°. We need number which is less than -920 and divisible by 360.

-1080 is less than -920 and divisible by 360.

The measure of angle D is

The measure of angle D is 160°. Therefore option B is correct.
