A length of rope is stretched between the top edge of a building and a stake in the ground. The head of
the stake is at ground level. The rope also touches a tree that is growing halfway between the stake and the
building. If the tree is 38 feet tall, how tall is the building?
38 ft.
19 ft.
76 ft.
57 ft.

    using similar triangles, it is clear that if the tree is halfway to the stake, then it is half as tall as the building.

    Assuming that the rope touches the top of the tree, that is.
