In x-y plane, there is a right triangle ABC (∠B=90o). If the length of AC is 25 and the slope of line segment AC is 4/3, what is the length of AB?	Select:
A) 12 B) 18 C) 20 D) 28 E) 40
Slope = 20hange in Vertical Direction/20hange in Horizontal Direction = 4/3   20hange in Vertical Direction = 4x = AB   20hange in Horizontal Direction = 3x = B20   AB^2 + B20^2 = 25^2   16x^2 + 9x^2 = 625   25x^2 = 625   x^2 = 25   x = 5   Therefore AB = 5*4=
