The ladder reaches 12 feet up the side of the building.
Solución
We have a right triangle where the ladder acts as the hypotenuse with a length of 13 feet, the distance from the building is one leg measuring 5 feet, and the height reached on the building is the other leg. According to the Pythagorean theorem:
(hypotenuse)² = (height)² + (base)²
Substituting the known values:
13² = (height)² + 5²
169 = (height)² + 25
Solve for (height)²:
(height)² = 169 - 25
(height)² = 144
Taking the square root of both sides gives:
height = √144
height = 12
Thus, the ladder reaches 12 feet up the side of the building.

Using the Pythagorean theorem, you can find how high the ladder reaches up the building. This theorem states that in a right triangle, the square of the hypotenuse (the ladder) is equal to the sum of the squares of the other two sides (the height of the building and the distance from the wall). So, we have: \(13^2 = h^2 + 5^2\) Which simplifies to: \(169 = h^2 + 25\) Now subtract 25 from both sides: \(h^2 = 144\) Taking the square root, we find that \(h = 12\) feet. Thus, the ladder reaches 12 feet up the building! And remember, when using ladders, always position them correctly to ensure safety—safety first!
