Final answer:
A polygon with a sum of interior angles of 720° has 6 sides.
Explanation:
Polygon Interior Angles: In a polygon, the sum of interior angles is given by the formula (n-2)180, where n represents the number of sides. Given that the sum of interior angles is 720°, we can solve for the number of sides: (n-2)180 = 720. Therefore, n = 6. So, a polygon with a sum of interior angles of 720° has 6 sides.
