I have figured it out.

Since we know where the line of action acts, we must find the magnitude of the moment (M) that makes it act at that location. If we take moments about point A, then (M) is equivalent to the actions of the two forces about point A.

So I broke the two forces into their components, force perpendicular distance... yadda yadda and I got the correct answer!
