Question

A kite is attached to a string of length 20

\sqrt{3}

m is tied to a pole on the level ground. If the string of the kite makes an angle of elevation of

60^{\circ}

with the ground, then the kite is flying at a height of 20 m.

Options:

A . True

B . False

Answer: Option B
:
B

A kite Is Attached To A String Of Length 20√3m Is Tied To...

s i n ∠ A C B = \frac{A B}{A C} \Rightarrow s i n 60^{\circ} = \frac{A B}{A C} \Rightarrow A B = A C \times s i n 60^{\circ} = 20 \sqrt{3} \times \frac{\sqrt{3}}{2} ∴ Height of the kite is 30 m .
