7 is b because x=pi/2 is not considered a solution since tan(pi/2) gives no solution.
so the only solutions are from tan=-2 (two solutions)

so sad cuz i put down 3 :(

For once my stupidity has actually paid off! :lol: I thought "meh, no idea how to solve" and drew a graph containing the tan thing and sin thing (don't judge me okay I've already said I'm a dumbass). And then looked to see all the places they intersected. By pure coincidence it's two. Woohoo!
