Atree is axed 8 feet above its base. when the tree fell to the ground, the tip of the tree lay 10 feet away from its base, as shown in the figure. determind the length of the part of the tree that was axed?

Well this seems easy enough well if the tree was cut 8 feet abouve the base and the tip is 10 feet away from the base wouldn't that make the part of the tree that was cut 10 feet away since it's 10 feet from the base which is 0 on a plane grid?

C. i possibility the answer to this
