A building is 3 ft from a 12-ft fence that surrounds the property. A worker wants to wash a window in the building 17 ft from the ground. He plans to place a ladder over the fence so it rests against the building. (See the figure.) He decides he should place the ladder 11 ft from the fence for stability. To the nearest tenth of a foot, how long a 5ft 12 ft ladder will he need? 11 ft 3ft He will need a ft ladder. (Type an integer or decimal rounded to the nearest tenth as needed.)
