Question

a 12 foot ladder is resting against a wall. the base of the ladder is 2.5 feet  from the base of the wall. how high up the wall will the ladder reach

anonymous · Answer

a^2 + b^2 = c ^2
2.5^2 + b^2 = 12^2
6.25 + b^2 = 144
minus 6.25
b^2 = 137.75
take the square root
b = 11.736694543 feet if you need to round 12 or 11.7
