Abuilding is 2 ft from a 7 - ft fence that surrounds the property . a worker wants to wash a window in the building 11 ft from the ground . he plans to place a ladder over the fence so it rests against the building . (see the figure .) he decides he should place the ladder 7 ft from the fence for stability . to the nearest tenth of a foot , how long a ladder will he need ?

The ladder is approx 14.21 feet long.

Step-by-step explanation:

The base of the ladder is 7 feet from the fence, which is 2 feet from the building, so it will be 9 feet from the building.

The top of the ladder will reach the window which is 11 feet from the ground.

In this way, we get a right triangle with the ladder as the hypotenuse, that we have to find.

Let the hypotenuse be x.

Using the Pythagorean Theorem, we get;

Hence, the ladder is approx 14.21 feet long.

answer: 414,377,008
