which of the following expressions will find the sum of interior angles of a polygon with 14 sides

Answer 1

To find the sum of the interior angles of a polygon with 14 sides, you can use the formula:

Sum of interior angles = (n-2) * 180

where n is the number of sides of the polygon.

So for a polygon with 14 sides, the expression would be:

(14-2) * 180 = 12 * 180 = 2160

Therefore, the expression that will find the sum of interior angles of a polygon with 14 sides is (14-2) * 180.
