I think you just use basic algebra for this.

-1.90 A is 1.9 times the length of vector A, and points in the opposite direction as vector A. So what direction does vector A point in, and what's its length?

doesnt give me anymore information then what is given. and i tried 59.1/1.9 to give me the answer but it said that was incorrect.

Shouldn't it be negative?

lsu777
yea i used the negative. i actually tried both ways and was told both were incorrect. only have one chance left.
