Chapter 12.3, Problem 21E

To determine

To find :themeasure of an exterior angle for thepolygon when the number of sides given.

Answer to Problem 21E

to measure of an exterior angle of regular polygon when number of sides given, then we put the value of n in the value where n is the number of sides of polygon.

The measure of an exterior angle of a regular polygon = $\frac{{360}^{\circ }}{n}$

Explanation of Solution

Given : consider, the informationprovided in the question,

Number of sides.

Formula used:

Each exterior angle for a regular n-gon has measure equal to $\frac{{360}^{\circ }}{n}$ .

to measure of an exterior angle of regular polygon when number of sides given, then we put the value of n in the value where n is the number of sides of polygon.

The measure of an exterior angle of a regular polygon = $\frac{{360}^{\circ }}{n}$

Hence, to measure of an exterior angle of regular polygon when number of sides given, then we put the value of n in the value where n is the number of sides of polygon.

The measure of an exterior angle of a regular polygon = $\frac{{360}^{\circ }}{n}$
