Another way to measure the height of a tree uses its shadow. The measurer walks away from the tree along its shadow until her head is in line with the top of the tree and the tip of the shadow. (FIGURE CAN'T COPY) Suppose that $C D=6$ ft and $B D=20$ ft. What other distance would you need to know in order to determine the tree's height?

You and a friend want to know how much rope you need to climb a large rock. Your friend is 5.5 feet tall and casts a shadow that is 18 feet long. If the rock casts a shadow that is 209.5 feet long, calculate the height of the rock from the ground. Round your answer to the nearest foot. (Hint: make a drawing) a. 64 ft b. 18 ft c. 210 ft d. 219 ft
