If you are 30 m from the foot of the Leaning Tower of Pisa, the top of the Leaning Tower is at

65 ° angle of elevation.. If the tower were perpendicular to the ground, we would could form a

right right triangle and easily obtain the height.. Unfortunately, the tower is inclined towards us

4 ". Calculate to find the height of the tower with such data?
