Question

Penn used the formula for the sum of the angles inside a polygon sum of the interior angles =(n-2)180 where n is the number of angles of the polygon.penne answer is 1,980 degrees.How many angles does the polygon have

Answer 1

13 angles

Explanation:

Sum of the angles of a polygon: S = (n-2)*180

1980 = (n-2)*180

1980 = 180n - 360

1980+360 = 180n

2340/180 = n

n = 13
