# Finding the Lean of the Leaning Tower of Pisa The famous Leaning Tower of Pisa was originally 184.5 feet high.* At a distance of 123 feet from the base of the tower, the angleof elevation to the top of the tower is found to be 60°. Find $\angle$RPQ indicated in the figure. Also, find the perpendicular distance from R to PQ.

Angle $\angle RPQ=84.{74}^{\circ }.$

The perpendicular distance from R to PQ is $183.72$ feet long.

See the step by step solution

## Step 1. Given Information

Height of Leaning tower of Pisa is 184.5m high.

The angle of elevation is found to be ${60}^{\circ }$at distance of 123 feet from the base of the tower.

We have to find $\angle RPQ$ and the perpendicular distance from R to PQ.
