40. The angle opposite the 80-foot side measures about 28.1°. Hasan and Parvani are considering changing the shape of their flower bed. It will still be a right triangle with the 150-foot side as 1 leg, but they will extend the 80-foot side until the angle opposite that side is about 40°. By about how many feet would they need to extend the 80-foot side ?

(Note: sin 40° ≈ 0.64, cos40° ≈ 0.77, tan40° ≈ 0.84)
