Question

a regular polygon has 20 sides. the measure of an exterior angle of this polygon is

Answer 1

Answer: 3240 degree is the measure of 20 sides polygon.

Step-by-step explanation:the formula for finding angle of any polygon is:

  sides - 2 x 180

20 - 2 x 180

=18 x 180 = 3240

Answer 2

Given:

Sides of the polygon=20

To find:

The exterior angle's measure

Solution:

The required measure is 18°.

We know that the polygon's exterior angle's measure can be obtained by dividing the complete angle by the number of the polygon's sides.

So, angle's measure=360°/number of sides

Using the values, we get

=360°/20

On dividing,

=36/2

=18°

Therefore, the required measure is 18°.
