Question

You are flying a kite and have left out 50M of string. The kites angle of elevation with the ground is 25°. If the strings stretch straight how high is the kite above the ground.

Round your answer to the nearest 10th of a metre.​

Answer 1

21.13 m

Explanation:

Height of the string, (Hyoptenuse) = 50 m

The kite makes an angle of elevation with the ground of 25°.

We need to find how high is the kite above the ground. Let it is h. We can find it using trigonometry as follows :

`\sin\theta=(P)/(H)\\\\h=H\sin\theta\\\\h=50* \sin(25)\\\\H=21.13\ m`

So, the required height is 21.13 m.
