Question

If the smallest angle of rotation for a regular polygon is 18, how many sides does polygon have?
10
12
20
24

Answer 1

Answer: There are 20 sides of a given regular polygon.

Step-by-step explanation:

To calculate the sides of a regular polygon, we use the equation:

$\text{Number of sides}=\frac{360^o}{\text{Smallest angle of rotation}}$

We are given:

Smallest angle of rotation = $18^o$

Putting values in above equation, we get:

$\text{Number of sides}=\frac{360^o}{18^o}\\\\\text{Number of sides}=20$

Hence, there are 20 sides of a given regular polygon.
