3 ft A building is 1 ft from a 9-ft fence that
surrounds the property. A worker wants
to wash a window in the building 12 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 7 ft
from the fence for stability. To the
nearest tenth of a foot, how long a
ladder will he need?
9 ft
7 ft
1 ft
He will need a ft ladder
(Type an integer or decimal rounded to the nearest tenth as needed.)
