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

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

x = 36

Step-by-step explanation:

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
