The sum of the measures of the interior angles of a regular heptagon is 900 degrees.
To find this, we can use the formula for the sum of interior angles of a polygon, which is (n – 2) × 180 degrees, where n is the number of sides. A heptagon has 7 sides.
So, we plug 7 into the formula:
(7 – 2) × 180 = 5 × 180 = 900 degrees.
This means that the total measure of all the interior angles in a regular heptagon adds up to 900 degrees.
