Answer 1

Answer:

28 feet.

Step-by-step explanation:

The ladder forms a right-triangular shape with the building.

The hypotenuse of the triangle = 53 feet

The height of the triangle = 45 feet

The base of the triangle = ?

According to Pythagorean theorem;

Hypotenuse squared = base squared + height squared

∴ base squared = hypotenuse squared - height squared = 53² - 45² = 784

base length = $\sqrt{784}$ = 28 feet.

So the ladder should be placed 28 feet away from the building.
