A 14-foot ladder is leaned against a wall. If the base of the ladder is 6 feet from the wall, how high up the wall will the ladder reach? Round your answer to the tenths place.

Answer 1

12.6 feet

h^2 = 14^2 - 6^2 = 196-36 = 160

It's a right triangle, hypotenuse (14) squared = sum of squares of the other two sides (6^2 + h^2)

h = sqr160 =12.64911064 rounds down to 12.6 feet
