The measure of each interior angle of a regular polygon is 135°. How many sides does the polygon have?
Show answer & explanation
Correct answer: B
Explanation
interior angle = 135°
Exterior angle = 180° − Interior angle
exterior angle = 360°/n
Exterior angle = 180 − 135 = 45°
360/n = 45
n = 360/45 = 8 sides
