Assuming that the Minnesota, the Mississippi and the Missouri battleships are standing still in Pacific Ocean. The Mississippi ship is 15.0 m due west of the Minnesota ship. The Missouri ship is 36.0 m from the Mississippi ship, in a direction 40.0° south of east from the location of Mississippi ship.
a- Find the distance between the Missouri battleship and the Minnesota battleship?
b- Find the direction of the Missouri ship's location from that of Minnesota ship?
