Question

What is the measure of an exterior angle of a regular 13-sided polygon?

Answer 1

$\bf \textit{sum of all exterior angles in a polygon}\\\\ n\theta =360\quad \begin{cases} n=\textit{number of sides}\\ \theta =\textit{angle in degrees}\\ ----------\\ n=13 \end{cases}\implies 13\theta =360\implies \theta =\cfrac{360}{13}$
