Answer
$m$ of the interior angles in a $16$-gon = $2520^{\circ}$
Work Step by Step
According to the Polygon Angle-Sum Theorem, the sum of all the measures of the interior angles of a polygon is $(n - 2)180$, where $n$ is the number of sides of the polygon.
We have a polygon that has $16$ sides.
$m$ = $(16 - 2)180$
Evaluate what is in parentheses first, according to order of operations:
$m$ = $(14)180$
Multiply to solve:
$m$ of the interior angles in a $16$-gon = $2520^{\circ}$
