Expert Solution & Answer
Check Mark

Answer to Problem 51SPR

The polygon has 9 sides.

Explanation of Solution

Given:

The measure of an interior angle of a regular polygon is 140.

Calculation:

The sum of the measures of interior angles of an n-sided polygon is:

  (n2)180

Let n be the number of sides in the polygon. As all the angles of a regular polygon are congruent, the sum of interior angle measure is 140n.

So, put the value in the formula:

  Sum=(n2)180140n=(n2)180140n=180n360360=40nn=36040n=9

The polygon has 9 sides.
