Mr. C has a sliding glass door leading to his backyard. Mr. C’s wife asked him to construct an awning above the door to prevent direct sunlight from coming in the sliding glass door and waking their napping children. The door is 7’ tall, the angle of elevation to the sun when the sunlight could potentially enter the house is 65° , the angle of depression for the proposed awning is 50° . How long must the awning be to prevent the sunlight from entering the door (The hypotenuse of the right triangle awning)?</p><p>50°</p><p>7’</p><p>65°</p><p>骣x 21.
