If you place a 34-foot ladder against the top of a building and the bottom of the ladder is 25 feet from the bottom of the building, how tall is the building? Round to the nearest tenth of a foot.

Respuesta :

Answer:

59

Step-by-step explanation:

Since it says round to the nearest tenth of a foot, I might be wrong. But anyways I hope this helps!

The height of the building that has a 34 foot ladder rested on it with a distance of 25 feet is 23.0 feet.

The situation forms a right angle triangle.

What is a right angle triangle?

A right angle triangle has one of its angles as 90 degrees. The isdes of the triangle can be found using pythagoras theorem.

Therefore, the length of the ladder is the hypotenuse of the triangle. The distance form the bottom of the ladder to the bottom of the building is the adjacent side.

The height of the building is the opposite side of the triangle. Therefore,

c² = a² + b²

34² - 25² = b²

b = √1156 - 625

b = √531

b = 23.0434372436

b = 23.0

The height of the building is 23.0 feet.
