EACH ANGLE OF A POLYGON IS 160 DEGREE. HOW MANY SIDES DOES IT HAVE? |
| Since it's a regular polygon, all the interior angles are equal, so they're all 160 degs. The sum of the interior angles of a polygon is 180*(n-2). Each angle is the total over n, in this case 160 degs. 160 = 180*(n-2)/n 160n = 180n - 360 -20n = -360 n = 18 sides |
