Question

"Find the sum of the measure of the interior angles and the sum of the measures of the exterior angles of the polgon."

Answer 1

In this case, the polygon has 12 sides, then, we can use the following general rule for the sum of interior angles of a polygon with n sides:

$S=180\cdot(n-2)$

then, we have:

$S=180(12-2)=180(10)=1800$

therefore, the sum of interior angles is 1800.

Also, as a general rule for any polygon, the sum of exterior angles is 360 degrees
