To find the Resultant vector in any direction,
add the magnitudes in that direction
call your direction along the + x axis, or EAST
then you have
case A:
40 East + 50 East = 90 East
case B
40 East - 50 East = - 10 East (which is + 10 West)
add the magnitudes in that direction
call your direction along the + x axis, or EAST
then you have
case A:
40 East + 50 East = 90 East
case B
40 East - 50 East = - 10 East (which is + 10 West)
