Answer :

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.
