Answer:

The ladder is approximately 12.65 feet high on the building.

Explanation:

Since the ladder forms a right triangle with the building, we can apply Pythagora's theorem to calculate the last side, this is done below:


14^2 = 6^2 + h^2\\h^2 = 14^2 - 6^2\\h^2 = 196 - 36\\h^2 = 160\\h = √(160)\\h = 12.65

The ladder is approximately 12.65 feet high on the building.
