Question

find the measure of an exterior angle of a regular octagon. sum = 360° x = ?°

Explanation:

Step1: Recall exterior - angle sum property

The sum of exterior angles of any polygon is $360^{\circ}$.

Step2: Divide by number of sides

A regular octagon has 8 sides. So, $x=\frac{360^{\circ}}{8}$.

Step3: Calculate the value

$x = 45^{\circ}$.

Answer:

$45$
