Question

a boy is standing on the ground and flying kite with 100m of string at an elevation of 30 degree . another boy is standing on the roof of a 10m high high building and is flying his kite at an elevation of 45 degree. both these boys are on opposite sides of both the kites. find the length of the string that the second boy must have so that the two kites meet

Answer 1

The height of the first kite above ground = 100 m * Sin 30 = 50 meters

Let the length of the second kite be : L meters

Height of 2nd kite:  L Sin 45 + 10 meters

So L sin 45 + 10 = 50 m
 => L = 40√2 meters

Answer 2

Answer:

40\/2 m
