Recently, about 70 metric tons of soil were removed from under a leaning
tower, and the angle the tower made with the ground was increased by about
0.7° Before that, a point near the top of the tower was 46.5 m from a point at
the base (measured along the tower), and this top point was directly above a
point on the ground 4.58 m from the same base point. See the given figure.
How much did the point on the ground move toward the base point?
The point on the ground moved m toward the base point.
