The formula for the sum of the interior angles of a polygon is:
S = (n-2) * 180
where S is the sum of the interior angles and n is the number of sides.
We are given that S = 720°, so we can substitute this into the formula:
720 = (n-2) * 180
Simplifying this equation:
4 = n-2
n = 6
Therefore, the polygon has 6 sides. Answer: B.6
