For the interior angle of a regular polygon to be greater than 130° then the exterior angle must be less than 50°.
The exterior angles of a regular polygon total 360°.
360/50 = 7.2 ....this needs to be rounded up to the next whole number.
Therefore a regular polygon with 8 or more sides has interior angles measuring 130° or greater.

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.
