An interior designer uses a regular pentagon shape for a tabletop. What is the measure of each interior angle?
Show answer & explanation
Correct answer: B
Explanation
Given:
Regular pentagon, n = 5
According to the formula:
Each interior angle = ((n − 2) × 180°) / n
Each interior angle = ((5 − 2) × 180) / 5
= (3 × 180) / 5
= 540 / 5
= 108°
Each interior angle = 108°
