2. [A3] Two ladders are leaned against a wall so that they make the same angle with the ground. The
taller ladder is 18 feet long. The shorter ladder is 10 feet long. The 10-foot ladder reaches 8 feet up
the wall. How much further up the wall does the 18-foot ladder reach? Label the diagram. Use
similar triangles to solve.

Robert plans to make a box-and-whisker plot of the following set of data. 27, 14, 46, 38, 32, 18, 21 find the lower quartile, the median, and the upper quartile of the set? lower quartile: 19.5; median: 29.5; upper quartile: 42 lower quartile: 14; median: 27; upper quartile: 46 lower quartile: 18; median: 27; upper quartile: 38 lower quartile: 16; median: 29.5; upper quartile: 42
