Question

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?

Answer 1

Answer:

Subtract 15.49 - 13.86 = 1.63 and then you simplify.

Answer 2

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..
