Question

A 12 foot ladder is set up 5 feet from the base of a building.How far up the building does the ladder reach? Round your answer to the nearest tenth of a foot

Answer 1

about 10.9 feet

Explanation:

Using the Pythagorean Theorem:

`{h}^(2) + {5}^(2) = {12}^(2)`

`{h}^(2) + 25 = 144`

`{h}^(2) = 119`

`h = 10.9`
