here u go as the answer 30 m

Answer 2

Answer:

30 meter away from the tree was the boy flying the kite.      

Step-by-step explanation:

Given : A boy was flying a kite which was at a height of 40 m just above a tree. The string was 50 m long.

To find : How far away from the tree was the boy flying the kite?

Solution :

According to question,

A right angle triangle ABC is form in which,

Refer the attache figure below.

AB=50 m is the length of the string be the hypotenuse,

AC=40 m is the height of the boy to tree be the perpendicular,

BC=x is the distance between tree was the the boy flying the kite be the base.

Applying Pythagoras theorem,

$AB^2=AC^2+BC^2$

$50^2=40^2+x^2$

$2500=1600+x^2$

$2500-1600=x^2$

$900=x^2$

$x=\sqrt{900}$

$x=30$

Therefore, 30 meter away from the tree was the boy flying the kite.
