    The interior and exterior angles of a polygon are supplementary. Therefore,

  2. 20 degrees

    The sum of the interior angles of a polygon is 180 (n – 2), where n represents the number of sides. The sum of the angles of a hexagon (six sides) is equal to

    Add the interior angles, set the sum equal to 720, and solve for x:
