# Completely messed up an answer to a question, what do I do?

I answered this question:

How to find the solutions $x$ of $2\sin{11^{\circ}}\sin{71^{\circ}}\sin{(x^{\circ}+30^{\circ})}=\sin{2013^{\circ}}\sin{210^{\circ}}$

but as you see, I completely misunderstood what OP was asking. I thought he meant he solved it in Wolfram by typing in the whole problem and it gave him the answer, where as (it seems) when he says he "can't use Wolfram", he means he can't use any kind of calculator and therefore he can't just type in $\arcsin (blah)$ into the calculator and solve it. So my answer is therefore apparently wrong and I got a down vote because of it.

I was just wandering what to do now. Should I delete it? Or should I leave it so other people can see my mistake and maybe put an edit on it saying what I thought the question was asking (I already have put a comment)?

Is there anything "protecting" me from downvotes or something because of the way OP didn't word the question properly?

I would like some feedback on this just so I understand how the site works a little better and so I can improve my answers. Thanks.
