The question is #4.a):

 

 

I know this is an ambiguous case, since we're given an angle and two sides. I solved for the triangle that's acute (with \(∠C = {86°}\)\(∠A = {27°}\), and side \(a = {6.0}\)m (opposite to ∠A)).

 

Except how should I solve for the obtuse triangle?

The answers in the textbook are \(∠C = {94°}\)\(∠A = {19°}\)\(a = {4.2}\)m

Are you talking about "4a" triangle with 12m, 13m, and the angle B=67 degrees?

The answer in your book doesn't make any sense!!!!
