In a six-sided polygon WQRSTV ∠W measures 48° less than the average (arithmetic mean) of the remaining five angles. What does ∠W equal to, in degrees?  Choose the correct choice from the following:	A) 72	B) 80	C) 88	D) 96	E) 104
The sum of interior angle in a polygon is (n-2)*180   so for a six sided figure, (6-2)*180 = 720   let the A.M of the other 5 angles be 'm'   --&gt; m*5 + W = 720, we know ∠W=m-48   --&gt; m*5 + m - 48 = 720, solving we get m=128   hence ∠W= 128-48=
