Question

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 angel made by the rope with the ground level is 30°.

Answer 1

hope it helps u.......

Answer 2

Cos30=distance btwn them/20
Root3/2=d/20
d=10 root3
Height^2=hyp^2-base^2
H=sq root of (20)^2-(10root3)^2
On solving,
H=10m
