An electrician wants to repair an electric connection on a pole of height 9m. He needs to reach 1.8 m below the top of the pole to do repair work. What should be the length of the ladder which he should use, when he climbs it at an angle of `60^(@)` with the ground? What will be the distance between foot of the ladder and foot of the pole?
