Answer 2

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.
