the sum of the interior angles of a polygon is 9540 how many sides does it have

OpenStudy (anonymous):

Recall that the sum of the interior angles inside an \(\large n\)-gon is \(\large 180(n-2)\). So what you want to do is solve \(\large 180(n-2) = 9540\) for \(\large n\). Can you take things from here? :-)
