Question

A kite is flying with a string of length $200\text{m}$. if the thread makes an angle ${30}^{\circ }$ with the ground, find the distance of the kite from the ground level. (Here, assume that the string is along a straight line)

Answer 1

Let $h$ denote the distance of the kite from the ground level.

In $△CAB,$

$\sin {30}^{\circ }=\frac{h}{200}$

$\Rightarrow h=200\sin {30}^{\circ }$

$\Rightarrow h=200\times \frac{1}{2}$

$\Rightarrow h=100\text{m}$

Hence, the distance of the kite from the ground level is $100\text{m}$.
