900 degrees.

Explanation: The sum of the measures of the interior angles of a heptagon is 900°. A heptagon has 7 sides. So to calculate the sum of the measures of the interior angles in a heptagon, substitute 7 for n in (n − 2) • 180°. You get (7 − 2) • 180°, or 5 • 180°= 900°.

The sum of the interior angles of any n-sided polygon is (2n - 4) right angles, ie 180n - 360 degrees. Where n = 7 this gives 1260 - 360 ie 900 degrees.
