The formula for the sum of the interior angles of an n-gon (a polygon with n sides) is 180 (n - 2).

The sum of the interior angles of a regular hexagon (n = 6) is 180(6 - 2) = 180 x 4 = 720.

The sum of the interior angles of a regular pentagon (n = 5) is 180(5 - 2) = 180 x 3 = 540.

So the difference is 180, which is the sum of the interior angles of a triangle.

Answer: A
