Q6 of 45 Page 137

A kite is flying at a height of 60 m above the ground. The string attached to the kite is tied at the ground. It makes an angle of 60° with the ground. Assuming that the string is straight, find the length of the string. (√3 = 1.73 )


Let AC be a string and kite is flying at point A, with height


AB = 60 m


Angle make by string with horizontal, θ = ∠ACB = 60°


Clearly, ABC is a right-angled triangle.


In ∆ABC






⇒ AC = 40(1.73)


⇒ AC = 6.92 m


Hence, length of string is 6.92 m
