Option D) 108 degrees
Step-by-step explanation:
We are given the following in the question:
A regular pentagon.
Thus, all the angles of the pentagon are equal.
Angle sum property of pentagon:
- In a pentagon, the sum of all the interior angle of a pentagon is 540 degrees.
Measure of each angle =

Thus, the measure of each angle on the sign is 108 degrees.
Option D) 108 degrees
