Two vertical poles are on either side of a road. A 30 m long ladder is placed between the two poles. When the ladder rests against one pole, it makes angle 32° 24' with the pole and when it is turned to rest against another pole, it makes angle 32° 24' with the road. Calculate the width of the road.
