Each exterior angle of a regular polygon measures 18°. What is the number of sides of the regular polygon.

Each exterior angle of a regular polygon measures 18°. What is the number of sides of the regular polygon. Correct Answer 20

Given:

Exterior angle = 18° 

Formula Used:

Number of sides of a regular polygon = 360°/(Measure of each exterior angle)

Calculation:

According to the question,

Each exterior angle of the regular polygon = 18° 

So, 

Number of sides of the regular polygon = 360°/(Measure of each exterior angle)

⇒ 360°/18° 

⇒ 20

∴ The number of sides of the regular polygon is 20
