Solution:
Draw a figure based on the instructions provided,
Let BC be the height of the kite from the ground, i.e., BC = 60 m
Inclined length of the string from the ground = AC, and
A is the point where the kite’s string is tied.
To Find: The value of AC i.e. the length of the string from the ground
From the above given figure,
BC/AC = sin 60°
⇒ 60/AC = √3/2
⇒ AC = 40√3 m
As a result, 40√3 m is the length of the string from the ground.
