The answer is "B" Here is a graph:
Drop a plumb bob from A to show a = 2c or c= a/2

Note to Guest..... A = B+1 AND it does not say A^2 - B^2 = 0
GIVEN : A = B+1
Then
A^2 - B^2 = (B+1)^2 - B^2 = B^2 +2B +1 - B^2 = 2B+1
A^2 - B^2 = 2B+1
But we want the SUM of the last two digits of the SUM of 8^25 + 12^25 NOT the sum of the last (single) digits of each term .....I realize the answer may be the same, but this method is not really a true method......
(700 - 7744 /4.5 ) / 32.2 = tan (theta)
theta= - 88.2 degrees
That is the maximum....actually, the ONLY C for a circle with area = 400 cm^2
There WERE 20 more people in A then B......then six people left......now there are only 14 more people in A than B....
THEN the six people went in to B.....Now there are only 8 more people in A than B.
