Based on the pattern in the table, what is the sum of the measures of the interior angles of a regular polygon with 22 sides?

Can someone please help me with this?

OpenStudy (cwrw238):

notice that the multiplier of 180 is n - 2 where n = number of sides in the polygon

OpenStudy (cwrw238):

so for a pentagon sum of int angles = 180 *(5 - 2) = 540 degrees

OpenStudy (cwrw238):

get it? just plug in n = 22 into the formula 180 ( n - 2)

Thank you.
