Question

a kite is flying at a height of 60 m above the ground the string attached to the kite is temporarily tied to the point on the ground beangli nation of the string with the ground is 60 degree find the length of the string assuming that there is no slack in the string

Answer 1

69.28m
by using sin60°=60m/length of string

Answer 2

Let BC = Height of the kite from the ground, BC = 60 m

AC = Inclined length of the string from the ground and

A is the point where string of the kite is tied.

To Find: Length of the string from the ground i.e. the value of AC

From the above figure,  

sin 60° = BC/AC

⇒ √3/2 = 60/AC

⇒ AC = 40√3 m

Thus, the length of the string from the ground is 40√3 m.
