A regular polygon has the sum of the interior angles as 3240degrees . find the number of sides the polygon has.

To find the number of sides a regular polygon has given the sum of its interior angles, you can use the formula:

Sum of Interior Angles = (n - 2) * 180 degrees

where "n" represents the number of sides.

In this case, we are given that the sum of the interior angles is 3240 degrees. Let's substitute the values into the formula and solve for "n":

3240 = (n - 2) * 180

To isolate "n", divide both sides of the equation by 180:

3240 / 180 = n - 2

Simplify the left side of the equation:

18 = n - 2

To isolate "n", add 2 to both sides of the equation:

18 + 2 = n

20 = n

Therefore, the regular polygon has 20 sides.
