∙ 12y ago
The sum of the interior angles of an n-gon is given by the formula (n-2)(180) where n is the number of sides of the polygon. Thus, the sum of the interior angles of an 18-gon is (18-2)(180) = 2880.

What is the sum of the measures of the interior angles of a heptagon?
To find the sum of the interior angles of a heptagon, use the formula (n-2) times 180 over n, where n is equal to the number of sides of the polygon.For a heptagon, which is a 7-sided figure, we plug in values to get (7-2) times 180, or 5 times 180 degrees, or 900 degrees.
