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.

The polygon has 9 sides

Step-by-step explanation:

We need to equate the given expression to the given value and solve for n.

The sum of the interior angles, s, in an n-sided polygon is given by the expression:

We want to use this formula, to calculate how many sides has a polygon if the sum of the interior angles is 1,260°.

We solve the following equation for n.

Divide through by 180 to get:

Add 2 to both sides to get:

Hence the polygon has 9 sides
