The Leaning Tower of Pisa in Italy leans because it was built on unstable soilâ€”a mixture of clay, sand, and water. The tower is approximately 58.36 meters tall from its foundation (see figure). The top of the tower leans about 5.45 meters off center.
Use the Law of Sines to write an equation for the length d of the shadow cast by the tower in terms of θ.
