do you know what vectors are and how they are added? do you know basic newtonian mechanics?

try drawing a picture, it should clarify things.

sorry I scrwed up (2i+5j)+(-8i-3j) I add the horizontal components then add the vertical components then simplify. I came up with 10 does this look right

which is the correct form of the vectors? in your first post it was 2i-5j and -8i-3j. that way the magnitude of the sum force is 10.
