A boy is flying a kite from ground with 75m of string at an elevation of 45∘. Another boy is standing on the roof of a 25 m high building and is flying his kite at an elevation of 30∘. Both the boys are on opposite sides of the two kites. Find the minimum length of the string that the second boy must have so that the two kites meet.
