If the sum of interior angles measures of a polygon is 720 degrees, how many sides does the polygon have?

The polygon has six (6) sides.

Step-by-step explanation:

We recall that the formula for the sum of the interior angles in a polygon is:

180° (n - 2)

Where n = number of sides

Since from the sum of the interior angles of the polygon is 720°

Then:

720° = 180° (n - 2)

We then solve for n

Divide both sides by 180°

720°/180° = 180° (n - 2)/180°

4 = n - 2

n = 4 + 2

n = 6

Therefore the number of sides of the polygon is 6 making it a hexagon.
