Sagot :

Given a regular 20-gon ( a 20 sided polygon )

The measure of each interior angle will be given by:

[tex]\frac{(n-2)}{n}\cdot180[/tex]

where n is the number of sides

Substitute with n = 20

So, the measure of each interior angle =

[tex]\frac{20-2}{20}\cdot180=\frac{18}{20}\cdot180=162[/tex]

The sum of exterior angles = 360

So, the measure of each exterior angle = 360/20 = 18
