A 10-foot ladder is leaning against a tree. The bottom of the ladder is 4 feet away from the bottom of the tree. Approximately how high up the tree does the top of the ladder reach?. . . A.. 2.4 feet. . B.. 6 feet. . C.. 9.2 feet. . D.. 10.8 feet
ladder=10 feet bottom of ladder=4 feet hight of tree=x by using pythogorean theorem h^2=altitude^2+altitude^2 10^2=4^2+x^2 100=16+x^2 84=x^2 taking sqrt on both sides 9.2=x hope this helps
