A ladder, with its foot in the street, makes an angle of 30 degrees with the street when its top rests on a building on one side of the street and makes an angle of 40 degrees with the street when its top rests on a building on the other side of the street. Then there is a 10 ft wide sidewalk on each side of the street. If the ladder is 50 ft long, how wide is the street?

52ft

72ft
