Answer:
x = 36°
Step-by-step explanation:
The sum of the exterior angles of a pentagon is always 360°. Since the pentagon is regular, meaning that all of its sides and interior angles are congruent, we know that all of the exterior angles are also congruent. Since a pentagon has 5 sides, we know that there are 5 congruent exterior angles, therefore:
5 * 2x = 360
10x = 360
x = 36°
