The Attempt at a Solution

From how I see this question, the joint at A has two reactions, one vertical and the other horizontal. The vertical one is zero, and the horizontal one should be 600N left. However, I got the feeling that I might have miss something. Did I do anything wrong? since the question looked too simple
