Geometry

Question Analysis:
This question tests understanding of exterior angles in regular polygons, specifically a pentagon.

Key Concept Explanation:
All regular polygons have equal exterior angles.
The sum of exterior angles for any polygon is always 360°.
For a regular pentagon (5 sides), each exterior angle = 360° ÷ 5.

Step-by-Step Solution:
Number of sides (n) in a pentagon = 5
Sum of exterior angles = 360°
Each exterior angle = 360° ÷ 5 = 72°
