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 the pole is 12 metre and the angle made by the rope with ground level is 30°. Calculate the distance covered by the artist in climbing to the top of the pole.

※ Clearly, distance covered by the artist is equal to the length of the rope AC.
⠀⠀⠀⠀⠀⠀⠀⠀
⟹ Let AB be the vertical pole of height 12m.
⠀⠀⠀⠀⠀⠀⠀⠀
※ It is given that ∠ACB = 30°
⠀
★ Thus, in right - angled triangle ABC, we have
- Perpendicular AB = 12m
- ∠ACB = 30°
and we wish to find hypotenuse AC.

Hence, the distance covered by the Circus artist is 24m.
