How many degrees in a oxagon?

An octagon has a total of 1,080 degrees. This is calculated by using the formula for the sum of the interior angles of a polygon, which is ((n - 2) \times 180), where (n) is the number of sides. For an octagon, (n = 8), so ((8 - 2) \times 180 = 1,080) degrees. Each interior angle of a regular octagon is 135 degrees.
