Answer:

≈ 19.1 feet

Explanation:

A right triangle is formed by the building , the ground and the ladder , that is the hypotenuse.

let x be the distance foot of ladder is from the building.

using Pythagoras' identity in the right triangle

x² + 34² = 39²

x² + 1156 = 1521 ( subtract 1156 from both sides )

x² = 365 ( take square root of both sides )

x =
√(365) ≈ 19.1 feet ( to the nearest tenth )
