Question

A boy is standing on the ground and flying a kite with 100 m of string at an

elevation of 30° . Another boy is standing on the roof of a 20 m high building and is

flying his kite at an elevation of 45° . Both the boys are on the 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

Plz Mark as the blainliest

Step-by-step explanation:

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
