A. Using this relationship, determine how tall Jacob's house is if the house's shadow measures 19.2 feet. Assume the triangles are similar.
B. Explain the concept of indirect measurement and how it is used in this situation.
C. There is a large tree in Jacob's front yard that measures 39 feet. Write out the steps to find the length of the tree's shadow, assuming it is similar.
