Coterminal angles CA to angle A may be obtained by adding or subtracting k*360 degrees or k* (2 Pi) if radian measure is given.
You were given an angle in degree measure not radian measure.
CA = A + k*360 degrees if A is given in degrees.
CA = -310 + 360
CA = 50 degrees is an angle with positive measure.
==================================================
To find an angle with negative measure, we use this:
CA = A - k*360 degrees
CA = -310 - 360
CA = -670
Final answer: 50 degrees and -670 degrees are coterminal with -310 degrees.
