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.
