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

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}=(360^o)/(18^o)\\\\\text{Number of sides}=20

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