Una escalera de 13 pies de largo se recuesta a una pared, de forma que la base de la escalera se encuentra separada de la pared, al nivel del piso, a una distancia de 5 pies. calcular la altura que llega la escalera en la pared. recuerde que en un triángulo rectángulo, la hipotenusa, elevada al cuadrado, es igual a la suma de los cuadrados de los otros lados. de ser necesario aproxime a la décima de pie

Step-by-step explanation:

The question in English is

A 13-foot long staircase rests on a wall, so that the base of the staircase is separated from the wall, at floor level, at a distance of 5 feet. Calculate the height of the ladder on the wall. Remember that in a right triangle, the hypotenuse, squared, is equal to the sum of the squares on the other sides. If necessary, approach the tenth foot

Applying the Pythagoras Theorem

Solve for h

For this case we have that, the Pythagorean theorem states:

In this case we have to:

We must find the height, that is, a.

Clearing we have:

Substituting:

So, we have that height is 12 feet.

ANswer:

12 feet
