The string of a kite is 120 metres long and it makes an angle of 60 degree
Afina-wow [57]

Answer:

103.92 m

Step-by-step explanation:

The kite is making right angle with the ground and its string is acting as hypotenuse of right triangle.

Let the height of the kite from the ground be h meters.

Therefore, by trigonometrical ratio:

\sin \theta \:  =  \frac{height \: of \: the \: kite}{length \: of \: the \: string}  \\  \\  \sin 60 \degree \:  = \frac{h}{120}  \\  \\  \frac{ \sqrt{3} }{2}  =  \frac{h}{120}  \\  \\ h =  \frac{ \sqrt{3} }{2}  \times 120 \\  \\ h =  \sqrt{3}  \times 60 \\  \\ h = 1.732 \times 60 \\  \\ h = 103.92 \: m \\

Thus, the height of the kite from the ground is 103.92 meters.
