    need part B please 1/2 points I Previous Answers A spaceship is traveling through deep space towards a space station and needs to make a course correction to go around a nebula. The captain orders the ship to travel 1.9 x 106 kilometers before turning 70° and traveling 1.7 x 106 kilometers before assuming the path towards the space station. If the captain had not ordered a course correction, what would have been the magnitude and direction of the path...
