One exterior angle of a regular pentagon has a measure of (2x) °. What is the value of x?

x = 18

x = 20

x = 30

x = 36

x = 36

Since the pentagon is regular, that means that all the sides are the same length. (To find the exterior angle of a regular pentagon do 360/n). Since a pentagon has 5 sides, we will do 360/5 which equals 72 degrees. 2x=72, so x=36.

The answer is D
