Convert the following degree measure into radians: 120 degrees. 200 degrees. 360 degrees. 150 degrees.

I'm not sure how to solve this problem.

Radians are alternate units used to measure angles in trigonometry. Just as it sounds, a radian is based on the radius of a circle. One radian is the angle created by bending the radius length around the arc of a circle.
We know that the degree of a circle is 3600.
The circumference of the circle is 2 \pi radians
So, 360 ^\circ= 2\pi radians
Dividing it with 2 on both sides,
180 ^\circ= \pi radians
120 ^\circ = \frac{2\pi}{3} radians
200^\circ = \frac{10}{9}\pi
