In the accompanying diagram, x represents the length of a ladder that is leaning against the wall of a building, and y represents the distance from the foot of the ladder to the base of the wall. The ladder makes a 60° angle with the ground and reaches a point on the wall 19 feet above the ground. Find the number of feet in x and y. x = (38√3) and y = (19√3)/3 x = (38√3)/3 and y = (19√3)/3 x = (19√3)/3 and y = (38√3)/3 x = (38√3)/3 and y = (19√3)
