Question

A Little boy is flying a kite. The string of the kite makes an angle of 30 degree with the ground. If the height of the kite is h=24m, find the lenght (in meters) of the string that the boy has used.

Answer 1

let the point at which the boy stand is C
let the point at which the kite flying is A
the height of kite is vertical from the ground then angle B makes 90° and we know that angle C is 30°
p/h = sin 30°=1/2
24/h=1/2
cross multiplying each other we get
h=48m
