Question

If the sum of the interior angle

of a polygon with n
measures
sides is 1800°, find n.
n = [?]
Hint: Sum= (n-2)180

Answer 1

The sum of the interior angles of a polygon with n sides is given by:

Sum = (n - 2) * 180

We are given that the sum of the interior angles is 1800 degrees. Setting these two expressions equal to each other, we get:

(n - 2) * 180 = 1800

Dividing both sides by 180, we get:

n - 2 = 10

Adding 2 to both sides, we get:

n = 12

Therefore, the polygon has 12 sides.
