Best Answer

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.

If it's a regular polygon then each interior angle measures 120 degrees.

The interior angle of any regular polygon can be calculated using the formula 180 * (n - 2) / n, where n is the number of sides. In this case, since each exterior angle measures 72 degrees, the interior angle would be 180 - 72 = 108 degrees. So the measures of the interior angles in this regular polygon would be 108 degrees.
