108?

How many angles does a pentagon have?

What is the total number of exterior angle degrees in a polygon?

To find the measure of an exterior angle of a regular pentagon, we can use the formula:

Exterior angle = 360 degrees ÷ number of sides

In this case, a regular pentagon has 5 sides, so:

Exterior angle = 360 degrees ÷ 5 = 72 degrees

Since none of the options given match the correct measure of 72 degrees, it seems there might be an error in the answer choices.

So, based on the correct formula and calculation, the measure of an exterior angle of a regular pentagon is 72 degrees, not 120.
