Question

The measure of each exterior angle of a regular polygon of $18$ sides is __________.

Answer 1

Explanation.

The measure of each exterior angle of a regular polygon is $\frac{360°}{n}$, where $n$ is the number of sides of the polygon,

Now, a polygon has $18$ sides, so $n=18$

The measure of each exterior angle of a regular polygon of $18$ sides is$\frac{360°}{18}=20°$

Hence, the measure of each exterior angle of a regular polygon of $18$ sides is $\underline{20°}$.
