So the green vector is the resultant force of P-Q?
There is no separate resultant force for a single vector which is what P-Q is.

But it is the resultant force of P and -Q.

The green vector is equal to P - Q. So you just need to find the length of the green vector using trig.

You could say that the green vector is the resultant of P and -Q if those were the forces acting on the particle.

The green vector is P - Q. Can you see why that is?

And does that help?
Yes it is making sense to me now, thanks
