Let the height of the building be x.
By using the Pythagorean theorem, we know that:
x^2 + 33^2 = 39^2
x^2 + 1089 = 1521
x^2 = 432
x = √432
x ≈ 20.8
Therefore, the building is approximately 20.8 feet tall.
If you place a 39-foot ladder against the top of a building and the bottom of the ladder is 33 feet from the bottom of the building, how tall is the building? Round to the nearest tenth of a foot.
