Question

What is the sum of the measures of the interior angles of a 12-gon?

A-1620°
B-1800°
C-1980°
D-2160

Answer 1

1800 degrees

Explanation:

Answer 2

we know that

The formula to calculate the sum of the measure of the interior angles in a polygon is equal to

`(n-2)*180\°`

where

n is the number of sides of the polygon

in this problem we have

`n=12\ sides`

substitute in the formula

`(12-2)*180\°=10*180\°=1800\°`

therefore

the answer is the option B

`1800\°`
