Restoration At the beginning of 1999, the Leaning Tower of Pisa leaned 14.5 feet past center and was in danger of falling over. Engineers tried removing dirt from the side of the tower opposite from the direction in which it leans, and were able to reduce the lean by about 10%. About how far past center did the tower lean after the dirt was removed?
