Question

Which polygon has an interior angle sum of 900°?

A polygon has 8 sides.
A polygon has 10 sides.
A polygon has 9 sides.
A polygon has 7 sides.

Answer 1

A polygon with an interior angle sum of 900° has 7 sides.

Step-by-step explanation:

A polygon with an interior angle sum of 900° has 7 sides.

To find the interior angle sum of a polygon, you can use the formula: (n - 2) * 180°, where n represents the number of sides of the polygon.

For a polygon with 7 sides: (7 - 2) * 180° = 5 * 180° = 900°.

Answer 2

A polygon that has 7 sides.

Step-by-step explanation:

S=(n-2)*180

n representing the sides

plug in each one into the formula and see which one = 900 degress.
