Question

What is the measure of an exterior angle for the regular polygon below?A. 270 degreesB. 45 degreesC. 135 degreesD. 180 degreesthank you :)

Answer 1

Solution

What is the measure of an exterior angle for the regular polygon below:

Number of sides = 8

The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides = 60

$\begin{gathered} \frac{360}{n} \\ =\frac{360}{8} \\ =45 \end{gathered}$

Therefore the measure of exterior angle = 45 degrees

Answer: Option B
