Can anyone help with this?? I need this grade but I just don't get it. Joshua has a ladder that is 12.8 ft long. He wants to lean the ladder against a vertical wall so that the top of
the ladder is 11 ft above the ground. For safety reasons, he wants the angle the ladder makes with the ground
to be no greater than 75°. Will the ladder be safe at this height? Show your work and draw a diagram to
support your answer.
