A biochip’s cover is designed as a regular polygon such that each interior angle is 165°. Find the number of sides.
Show answer & explanation
Correct answer: D
Explanation
Given:
Each interior angle = 165°
By the formula:
Each interior angle = ((n − 2) × 180) / n
165 = ((n − 2) × 180) / n
165n = 180n − 360
360 = 180n − 165n
360 = 15n
n = 360 / 15
n = 24
