Joshua has a ladder that is 11 ft. long. He will lean the ladder against a vertical wall. For safety reasons, he wants the angle the ladder makes with the ground to be no greater than 65°. Is it possible for Joshua to lean the ladder against the wall so that the top of the ladder is at least 10 ft. above the ground? Show your work and draw a diagram to support your answer.
