3. A 10-foot ladder is placed against the side of a building as shown in figure 1 below. The bottom of the ladder is 8 feet from the base of the building. tn 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? Show how you arrived at your answer. 10 Feure 1 Figure 2
