      A circus artist is climbing a 20 m long rope, which is tightly stretched and tied from the top of a vertical pole to the ground. Find the height of the pole, if the angle made by the rope with the ground level is 30°.

      In the given figure, AB is pole and AC is rope.
      In ΔABC,
      AB/AC = sin30⁰ ⇒ AB/20 = 1/2 ⇒ AB = 20/2 = 10
      Hence, the height of the pole is 10 m.
