Question

A polygon has an interior angle sum of 2520 degrees. How many sides must the polygon have?

Answer 1

So since the formula for the sum of a polygon's interior angles is (n-2)180, just make that equal to 2520 and solve for n, which is the number of sides.

STEPS:

1) (n-2)180 = 2520

2) n-2 = 2520/180

3) n-2 = 14

4) n = 16

So the polygon must have 16 sides

Answer 2

The polygon must have 16 sides.

Step-by-step explanation:

Given :

A polygon has an interior angle sum of $2520^\circ$.

Solution :

For a polygon,

$\rm (n-2)\times 180^\circ = 2520^\circ$

$\rm n- 2 = 14$

$\rm n = 16$

The polygon must have 16 sides.
