1. ## [SOLVED] Vector problem

The problem is A+B+C
and when i connect them the reactant doesn't fit

The other problem is A-B-C with the same vectors

this is how i solved A-B-C i dont even know were to put the resultant on this one

Am i doing something wrong or is this like a trick problem?

I think also i might be over thinking this beacuse all the arrows are slightly tilted.

The tail of the resultant vector is the tail of the first vector of the sum : $\vec{a}$. It's head is the head of the last vector of the sum : $\vec{c}$. Using this :

What you've done is correct. To find the resultant vector $\vec{a}-\vec{b}-\vec{c}=\vec{a}+(-\vec{b})+(-\vec{c})$ you only have to connect the tail of the first vector of the sum with the head of the last one.

3. so it would look like this?
