Hard Geometry Polygons

In a regular polygon with 20 sides, the measure of each interior angle can be calculated using the formula:

$$ A =\frac{(n - 2) imes 180^ ext{o}}{n} $$

where $n$ is the number of sides.

Given this polygon, what is the measure of each interior angle?

A

$162^ ext{o}$

B

$144^ ext{o}$

C

$150^ ext{o}$

D

$158^ ext{o}$
