Question

A Polygon has a sum of interior angle measures equal to 1620°. How many sides does the polygon have?​

Answer 1

Answer:

The polygon has 11 sides.

Step-by-step explanation:

The sum of the interior angles, in degrees, of a regular polygon is given by the formula 180(n – 2), where n is the number of sides,

so, 1620=180(n – 2)

     1620/180=n-2

=>  9=n-2

therefore,n=11

Answer 2

The polygon has 11 sides
1620=180(n-2)
1620/180=n-2
=9=n-2
Therefore = 11
