There is no regular polygon with an interior angle of 20o. If the interior angle is 120o then there are six sides and the sum of the angles is 720o.
360 degrees
The sum of the interior angles of a polygon with n sides is 180*(n-2) degrees.
The polygon would have 10 sides.
(number of sides -2)*180 = sum of interior angles

There is no regular polygon with an interior angle of 20o. If the interior angle is 120o then there are six sides and the sum of the angles is 720o.
360 degrees
The answer is 11 sides If a polygon with 10 sides the sum of the interior angles are 1440° So 1440°+180°= 1620°
24 sides
It will have 26 sides
