you and a friend are on the 10th floor apartment buildings that are directly across the street from each other, and have balconies. The two of you are making a banner to hang between the apartment buildings. The banner must cross the street. To hang the banner you and your friend need to attach it to hooks on the wall of each balcony The wall on your balcony is 6 ft away from the street and the wall of your friends is only 4 ft away from the street. You also know that your friends balcony is 10 ft away from the end of his building and you balcony is 100 ft away from the edge of you building. How wide is the street between you and your friends apartment buildings? How long does the banner need to be?
