A pentadecagon is a polygon with 15 sides. The sum of the interior angles of a pentadecagon can be calculated using the formula ((n - 2) \times 180) degrees, where (n) is the number of sides. For a pentadecagon, this gives ((15 - 2) \times 180 = 13 \times 180 = 2340) degrees. Therefore, the sum of the interior angles of a pentadecagon is 2340 degrees.
