Yes. A central angle is equal in degrees to the measure of the arc it subtends. If the arc is x degrees, the central angle is x degrees.

The measure of the central angle in radians is equal to the length of the arc divided by the radius. To convert the angle's measure from radians to degrees recall that 180 degrees is equal to pi radians.
