Which expression finds the measure of an angle that is coterminal with a 126° angle?

a. 126° + (275n)°, for any integer n
b. 126° + (375n)°, for any integer n
c. 126° + (450n)°, for any integer n
d. 126° + (720n)°, for any integer n

The expression that gives an angle that is coterminal with 126 is 126 + 720n. Two angles are said to be coterminal if when they are drawn in a standard position, their terminal sides are on the same location. The expression will give an angle which when it is drawn the terminal sides are on the same location with the 126 angle.
