Thanks! But our teacher has advised us to use what we've learned about so far and we've been taught the law of sines, cosines, and basic cosine/tangent/sine.

Please inform your teacher (if necessary) that Common Sense must never be ruled out. Therefore my reasoning in my first paragraph settles the question definitively.  The question DOES NOT ask for any areas.  You (and I) can tell which triangle will have the greater area.
