O is the origin from the cartesian plane .From the origin O take pointA in the north-east direction such that |OA|=5, B is a point in the north-west direction such that |OB|=5 then |OA-OB| is

North west direction means = 45° from upwards in anti clockwise direction
North east direction = 45° from upwards in clockwise direction
But |OA| = |OB| = 5 units
Hence OAB makes a triangle
Where angle O is 90 degree and this is also a isosceles triangle.
Hence |OA- OB| = 5\large \sqrt2
