(adsbygoogle = window.adsbygoogle || []).push({}); URGENT Trig question

Okay I missed this lesson, so I dont really know what to do. I know it has to do with law of Sines/Law of Cosines. (but I think I can do all the parts involving that)

1)First Decide how many triangles can be drawn based on the information (my edit: I can do this)

2)then draw it or them as accuratly as possible (My edit: I can do the "it" part its the second half of the them part thats the problem)

3)Solve for any missing side or angle in any triangle drawn. (I can do this when I get that far)

4)Find the area of each triangle to the nearest integer (Thats easy)

problems:

1) In Tri. ABC m<A=30, a=7, b=8

Okay, because b>a>bSinA I know that two triangles can be drawn from this information.

I can draw and find all of the information (Including the area) for the first triangle. What I cant do is find how to draw the second triangle. I talked to my friend and she said it was really easy and all I had to do was to find the referance 30 in quad. 2, and that would be the obtuse angle of my triangle. However, I have no idea what to do beyond that. I think she must have left out a couple of steps. (It was a quick conversation)

If I merely replace <A with 150 then no triangle can be drawn from the given information.

Ok, I'm lost, any help?
