Qt A
From figure 1, we can deduce b = 80
6b = 6 * 80 = 480
Qt B
Sum of interior angle of polygon = 180 ( n - 2 ) (n = no of angle )
sum = 180 ( 5-2 ) = 540
Qt B > Qt A
Answer B
From figure 1, we can deduce b = 80
6b = 6 * 80 = 480
Qt B
Sum of interior angle of polygon = 180 ( n - 2 ) (n = no of angle )
sum = 180 ( 5-2 ) = 540
Qt B > Qt A
Answer B

A)The quantity in Column A is greater.
B)The quantity in Column B is greater.
C)The two quantities are equal.
D)The relationship cannot be determined from the information given.
\(b = 80\) ..... (Vertically opposite angles are equal)
Sum of all interior angles in a Polygon = \((n - 2)(180)\), where \(n\) is number of sides
Col. A: \(6(80) = 480\)
Col. B: \((5 - 2)(180) = 540\)
Hence, option B
