**Reiny**, Monday, May 30, 2011 at 10:11pmThe wording is somewhat ambiguous. The way I read it says that the part that fell off must be 5/8 of the tree

so (5/8)x = 40

5x = 320

x = 64

or

Is the part that broke off still attached and when bent over lands 40 feet from the tree?

then (3x/8)^2 + 40^2 = (5x/8)2

9x^2/64 + 1600 = 25x^2/64

(16/64)x^2 = 1600

take √ of both sides

(1/2)x = 40

x = 80
