Question 884694: Each interior angle of a regular polygon is 160. Fin the number of its sides and sum of interior angle of the polygon Answer by fcabanski(1391) (Show Source):
You can put this solution on YOUR website! a + 360/n = 180. a is the size of the interior angles of the regular polygon, and n is the number of sides.
160 + 360/n = 180
360/n = 20
n = 360/20 = 18 sides.
The sum of interior angles is 18 * 160 = 2880 degrees.
