A 13-foot ladder is placed against a vertical wall of a building, with the bottom of the ladder standing on level ground 5 feet from the base of the building. How high up the wall does the ladder reach?
The ladder reaches feet up the wall.
169- 25 = 144 [tex] \sqrt{144} [/tex] Sqaure root of 144 is 12 so If we plug that in.. 25 + 144 = 169 5^2 + 12^2 =13^2 This all checks out ~Hope This helps
