Question

The sum of the interior angles, s, in an n-sided polygon can be determined using the formula s=180(n-2), where n is the
number of sides.
Using this formula, how many sides does a polygon have if the sum of the interior angles is 1,260°? Round to the nearest
whole number.
O 6 sides
O 7 sides
O 8 sides
O 9 sides​
