Geometry

= = = = = = = = In the Wikipedia entry on the Leaning Tower of Pisa, it says, "The height of the tower is 55.86 m (183.27 ft) from the ground on the lowest side and 56.70 m (186.02 ft) on the highest side.... [after] the restoration work between 1990 and 2001...the tower leans at an angle of 3.99 degrees. This means that the top of the tower is 3.9 metres (12 ft 10 in) from where it would stand if the tower were perfectly vertical." Does this make sense? Why or why not?
