Question

find the measure of each exterior angle of regular polygon of 9 side

Answer 1

measure of an exterior angle * no. of sides = 360
360/9= 40 degrees
hope it helped you

Answer 2

Given:

• Side of polygon = 9 sides

To Find:

The measure of each exterior angle.

Formula:

Sum of angles a regular polygon = $(x=2) \times 180^{o}$

Solution:

According to the question,

Sum of angles a regular polygon having side 9 = $(9-2) \times 180^{o}$

$\implies 7 \times 180^{o} =1260^{o}$

∴ Each exterior angle = $\frac{1260}{9} = \boxed{ 140^{o}}$

Hence, each exterior angle will be 140 degree
