So I’m trying to do this question but I’m really confused. Isn’t there supposed to be only 2 solutions due to the tan graph only shows two? I put a picture of what I mean also the mark scheme. I got two solutions because I just added 180 to the first answer. The solutions I got were 54.7 and 234.7. This is always how I’ve done it because I look at the graph and see how many solutions I can see but the mark scheme shows additional two solutions

+/- root 2 bc we have square rooted
since its an equation we have to consider the negative option too
and negative root 2 has itself 2 solutions in the range
