A 10foot ladder is placed against the side of a building, as shown in Figure 1. The bottom of the ladder is 8 feet from the base of the building. In order to increase the reach of the ladder against the building, it is moved 4 feet closer to the base of the building, as shown in Figure 2. To the nearest foot, how much further up the building does the ladder now reach?
