Question

A kite is flying at a height of $30m$ from the ground. The length of string from the kite to the ground is $60m.$ Assuming that there is no slack in the string. find the angle of elevation of the kite at the ground.

Answer 1

Perpendicular$=30$m

Hypotenuse$=60$m

$\theta =?$

$\sin \theta =\frac{P}{H}$

$=\frac{30}{60}$

$\sin \theta =\frac{1}{2}$

So $\sin \frac{1}{2}={30}^o$

So $\theta ={30}^o$.
