# 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.
