A person who is 5 feet, 6 inches (5.5 feet) tall casts a shadow (from N to S) that is 12 feet long. The distance along the ground from the person (N) to the flagpole (G) is 18 feet. Find the height of the flagpole (FG) showing all calculations.
What is the length of SP and PF?
ratio of height to shadow length is the same for both
5.5/12 = FG/length of flagpole shadow
I do not have your diagram so I do not know if the flagpole shadow is 18 feet or 18+12 or whatever
