An old lady, to maintain her health during morning walk, covers three displacements. The first has a magunitude of 200 m and makes an angle of 110 with the positive x axis. She covers second displacement wich has magnitude of 300 m at an angle of 20 west of south and then she covees third displacement. The resultant displacement has magunitude of 420 m and is direct at an angle of 45.0 to the positive x axis. Find the magunitude and direction of third displacement
