One exterior angle of a regular pentagon has a measure of 2 x degrees What is the value of x ?

The exterior angles of any polygon add up to 360 degrees. A regular pentagon has five equal exterior angles, so each measures 360 ÷ 5 = 72 degrees. Since the angle is 2x degrees, 2x = 72, giving x = 36. The correct choice is “x is equal to 36.”
