Question

A ladder that is 14 feet long is placed against a building. The bottom of the ladder is 6 feet from the base of the building. A right triangle with side length 6 feet, hypotenuse 14 feet, and side h. In feet, how high up the side of the building is the top of the ladder? Round to the nearest tenth of a foot.

Answer 1

12.6

Explanation:

I rounded to the nearest tenth of a foot like it said to :)

Answer 2

The ladder is approximately 12.65 feet high on the building.

Explanation:

Since the ladder forms a right triangle with the building, we can apply Pythagora's theorem to calculate the last side, this is done below:

`14^2 = 6^2 + h^2\\h^2 = 14^2 - 6^2\\h^2 = 196 - 36\\h^2 = 160\\h = √(160)\\h = 12.65`

The ladder is approximately 12.65 feet high on the building.
