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 building is 40 ft tall, how tall is the tree? (3 points) Responses 10 ft 10 ft 20 ft 20 ft 80 ft 80 ft 18 ft
The height of the building is given as 40 ft. Since the rope touches the tree that is halfway between the stake and the building, we can divide the height of the building by 2 to find the height of the tree.
40 ft รท 2 = 20 ft.
Therefore, the height of the tree is 20 ft.
