Q3 of 35 Page 219

A circus artist is climbing from the ground along a rope stretched from the top of a vertical pole and tied at the ground. The height of pole is 10 m and the angle made by the rope with ground level has measure 30. Calculate the distance covered by the artist in climbing to the top of the pole.

Let PQ be the pole, whose height is 10 m and PR be the length of a rope stretched from the top of a vertical pole. The artist is moving from R to P.



The angle made by the rope with ground level has measure 30⁰.


∠PRQ = 30⁰


In ∆PQR,




PR = 10 × 2


= 20 m


The distance covered by the artist in climbing to the top of the pole is 20m.

An electrician has to repair an electric fault on the pole of height 5 m. He needs to reach a point 2 m below the top of the pole to undertake the repair work. What should be the length of the ladder that he should use, which when inclined at an angle of measure 60 to the horizontal would enable him to reach the required position.
