Maggie puts together two isosceles triangles so that they share a base, creating a kite. Each leg of the upper triangle measures

Wittaler [7]

(See attached)
AO^2 = side a^2 - BO^2
AO^2 = 41^2 -40^2
AO^2 = 1,681 -1600
AO^2 = 81
AO = 9

DO^2 = side b^2 -BO^2
DO^2 = 50^2 -40^2
DO^2 = 2,500 -1,600
DO^2 = 900
DO = 30

Diagonal AD = AO + DO = 9 + 30 = 39 inches
