What is the question?
Is that symbol an S?
Do you need to tell either compression or tension are acting on members 1 and 2?

To find forces in member 1 and 2 that is all, yes I just choose S as a symbol

I have obtained similar results via graphical vectorial addition.
The angles in your diagram are not at scale, which gave me the initial impression that member 2 would be working in compression mode.
However, both structural members are working under tension to resist the action of resultant force from F1 and F2 combination (approximately 6250 N at 40° from horizontal).

I confirm your answers, but it is easier if you resolve normally to each reaction force in turn. That gives you one equation to solve for each separately instead of having to solve simultaneous equations.

Yeah and when I see it now I see it would have been easier to just use the angles close to the x-axis
