(Sine Law)Is the ambiguous case only used on the angle you just found? For example, if I had two solutions for a triangle, found an angle for Case 1, is that my new reference angle?

Directrix (directrix):

I'm not sure. Would you post the actual ambiguous case problem that caused you to post this question? Thanks.

OpenStudy (homeworksucks):

Ok, umm give me a sec

OpenStudy (homeworksucks):

And we're solving for the bottom side

OpenStudy (homeworksucks):

I'm wondering which side would be the reference angle

OpenStudy (homeworksucks):

which angle sorry

OpenStudy (homeworksucks):

Would it be 35, or the ones that I find after that?

Directrix (directrix):

@Homeworksucks Please post the work you have done on this problem so far.

OpenStudy (homeworksucks):

So I figured that there would be two solutions, because \[a >b \sin(A)\]

OpenStudy (homeworksucks):

And then found the angle adjacent to 35 to be 58 degrees

OpenStudy (homeworksucks):

Then subtracted the angles by 180 to find the other one

OpenStudy (homeworksucks):

87 degrees,

OpenStudy (homeworksucks):

Then found the bottom side using the sine law to 522.3

OpenStudy (homeworksucks):

My question is, how do I know which one to consider as the obtuse angle when finding the case 2 triangle?

Directrix (directrix):

Let me see what I get. Hold on.

Directrix (directrix):

My first pass at the problem -- 2 triangles First: 52.8 degrees, 92.19 degrees, and 627.18 for the side Second: 127.19 degrees, 17.81 degrees, and 191.97 for the side
