Challenge! Ready? Michele wanted to measure the height of her school’s flagpole. She placed a mirror on the ground 48 feet from the flagpole, then walked backward until she was able to see the top of the pole in the mirror. Her eyes were 5 feet above the ground and she was 12 feet from the mirror. Using similar triangles, find the height of the flagpole to the nearest tenth of a foot. Write out the answer so I, Lolly, know you are not cheating.

    You need to make a proportion to figure out the length of the side you're missing.

    Since they are similar triangles, the sides are proportional. What would be the proportion?
