The measure of each exterior angle of a regular polygon of 15 sides is _____.

We know that the measure of each exterior angle of a regular polygon is $\frac{{360}^o}{\mathrm{n}}$.

Where ‘n’ is the number of sides of the polygon.

Given, the number of sides of the polygon is 15.

So, the measure of each exterior angle $=\frac{{360}^o}{15}={24}^o$
