An aeroplane takes flight from a place towards another place in direct

1.	An aeroplane takes flight from a place towards another place in directiontheta N of E in a strong wind of velocity U to the west. The speed of plane in still air is V. Distance the two places is L At what angle the plane must be driven wrt line of flight
Answer» `SIN^(-1)(u/v sin THETA)` `sin^(-1) (v/u sin theta)` `cos^(-1) (u/v sin theta)` `Tan^(-1) (u/v sin theta)` ANSWER :A
