Find the degree measure of the angle whose radian measure is -1.8 pi.

In the SI system, the radian is taken as the main unit for measuring angles.

The radian measure of the “pi” angle corresponds to its degree equivalent of 180 °.

Knowing this ratio, we can easily find the degree equivalent for the radian measure of 1.8 pi.

1.8 * 180 ° = 324 °.

Answer: 324 °.
