we know that
The formula to calculate the sum of the measure of the interior angles in a polygon is equal to
[tex](n-2)*180\°[/tex]
where
n is the number of sides of the polygon
in this problem we have
[tex]n=12\ sides[/tex]
substitute in the formula
[tex](12-2)*180\°=10*180\°=1800\°[/tex]
therefore
the answer is the option B
[tex]1800\°[/tex]
