A51-foot ladder is leaning up against a building . the top of the ladder reaches the wall at a height of 50 feet . how far is the bottom of the ladder from the building
Answers: 1
feet or 10.05 feet.
, where h is the height of the wall , l is length of ladder and b is the distance of bottom from the building.![(51)^2=(50)^2+b^2\\\\\Rightarrow\ b^2=(51)^2-(50)^2\\\\\Rightarrow\ b^2=2601-2500=101\\\\\Rightarrow\ b=\sqrt{101}=10.0498756211\approx10.05\ \text{[ Rounded to the nearest two decimal places. ]}](/tpl/images/0160/3732/b87ff.png)
