Mrs. Robinson assigned her class a project to find the height of the flagpole. The students could not easily measure the helght, so they had to use their knowledge of similar triangles to determine the height of the flagpole. One student placed a mirTor on the ground 21 feet from the base of the flagpole and backed up until the reflection of the top of the pole was centered in the mirror. Part A: If the student is 5.4 feet tall and is standing 7.2 feet from the mirror, how tall is the flagpole?
