A 16-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. In order to increase the reach of the ladder against the building, the ladder is moved 4 feet closer to the base of the building, as shown in Figure 2. To the nearest foot, how much farther up the building does the ladder now reach?

Well if the ladder is moved 4 feet closer to the building then that should mean that it moves 4 feet higher. because the ladder is 8 feet from the base of the building you just do

8 + 4 = 12

so it's 12 feet ... ?

hope this was right on not sure ...
