)X and Y live in a North-South parallel street. X travels 10 km towards North to reach the east-west street . Y travels 6 km towards south to reach the east –west street . X travels now 4km towards east and y travels 8km towards west and they met each other. What is the distance between x and y?
RE: )X and Y live in a North-South parallel street. X ...
ans is 20.7, as X moves to north then east it makes a angle of 90deg so we can get the length of hypotaneous, similarla for y we can get the length of hypotaneous..
adding up these two length gives us the actual distance between X and Y
