1. The problem statement, all variables and given/known data The leaning tower of Pisa was originally perpendicular to the ground and 179ft tall. Because of sinking into the earth, it now leans at a certain angle 'theta' from the perpendicular, as shown in the figure. When the top of the tower is viewed from a point 150ft from teh center of its base, the angle of elevation is 53 degrees. a) Approximate the angle theta. b) Approximate the distance d that the center of the top of the tower has moved from the perpendicular. Here is the photo. I apologize for the blurry photo. If needed I'll try to get my real camera and take a better one. 2. Relevant equations Law of Sines. Maybe one can solve this by other means, but it is implied I can do this with Law of Sines alone. 3. The attempt at a solution I know the height of the tower is the the length of one side of the right triangle (the straight line on the tower in the photo). I'm not sure if that is also true for the line the represents how the tower leans. I'm not sure where to start with this as a result. I think I need a nudge in the right direction. Thanks!
