    157.5 degrees.

    Step-by-step explanation:

    2520=180*14. To match the 180 * (n-2) of the theorem, n-2 = 14 or n=16.

    Each interior angle of a regular hexadecagon (16-sided) is 2520/16 = 157.5 degrees.

    16 sides

    Step-by-step explanation:

    Sum of Angles in Polygon = 180 (n-2)

    2520 = 180 (n-2)

    n-2 = 14

    n = 16

    n = sides in polygon
