I want to Problem 2 above, the equilateral triangles on the left and content of the problem on the right. Moreover, the total widths of the two minipapes equal to width of the page. How do I do that? Thank you.

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, visit the help center. If this question can be reworded to fit the rules in the help center, please edit the question.

Welcome to TeX.sx! Please trim your question to a minimal working example (MWE) that illustrates your problem. –  Matthew Leingang Oct 8 '12 at 14:35
I tried, but I can not. –  minthao_2011 Oct 8 '12 at 14:47
@minthao_2011 Have a look at the resources Matthew linked you to! Without a proper MWE, your question will most likely be closed. –  doncherry Oct 9 '12 at 18:57

Here's one possibility; I used t for the optional argument for the minipages (to get top vertical alignment) and baseline=(current bounding box.north) for the tikzpicture. I also removed a spurious blank space after the first \end{minipage} so that now the width for both minipages can add up to \linewidth. Also I used font=\scriptsize for the nodes of the diagram. Depending on the desired position for the label "Problem " one can obtain different alternatives; the following code shows two possibilities:

\item $(\sqrt{3}\sin x + 2\cos x)\cdot (1 - \cos x) = \sin^2 x$.

As a personal note, perhaps you could reconsider the change for \baselinestretch?

Another request has been made in a comment: the problem to the left, the figure to the right:

I'd move the whole pro environment inside the second minipage, adding \noindent in front of the first one. But that depends on where "Problem 2" is desired. Probably the best is to have the figure on the right. –  egreg Oct 8 '12 at 14:57
@egreg yes, that's another option; I'll add it to my answer. –  Gonzalo Medina Oct 8 '12 at 15:01
Thank you very much. –  minthao_2011 Oct 8 '12 at 15:06
How can I put the the figure on the right and the content of problem on the left? Please help me. –  minthao_2011 Oct 9 '12 at 4:55
@minthao_2011 please see my updated answer. –  Gonzalo Medina Oct 9 '12 at 18:27
