In x-y plane, there is a right triangle ABC (∠B=90o). If the length of AC is 225 and the slope of line segment AC is 4/3, what is the length of AB?  Choose the correct choice from the following choices
A) 12 B) 180 C) 24 D) 28 E) 40
Slope = Change in Vertical Direction/Change in Horizontal Direction = 4/3   Change in Vertical Direction = 4x = A180   Change in Horizontal Direction = 3x = 180C   A180^2 + 180C^2 = 225^2   16x^2 + 9x^2 = 225^2   25x^2 = 225^2   x^2 = 25*9^2   x = 45   Therefore A180 = 45*4=
