A 12 foot ladder is placed against the side of a building,
forming a right triangle as shown in Figure 1 below. The
bottom of the ladder is 7 feet from the base of the building.
In order to ingrease the height to which the ladder reaches,
the ladder is moved closer to the base of the building,
increasing the angle the ladder makes by the ground by 20°
as shown in figure 2.
