The ladder along with the wall and the floor would form a right angled triangle. The ladder would be the hypotenuse so you know the length of the hypotenuse as 27 ft. 
Now sin 47 = (Height of the tip of the ladder from the floor)/(Length of the ladder)

So use that equation to find the height of the tip of the ladder from the floor.
