Why do you show lengths of two a's?
One is <A 30 degrees and a is 9 cm
I got obtuse for the answer

because it is also a correct choice.

After doing your 3:00 pm post, I realized that you are working with the ambiguous case
so angle B could be either 26.4° or 153.6°
so the triangle could be either acute OR obtuse, choice #4
so angle B could be either 26.4° or 153.6°
so the triangle could be either acute OR obtuse, choice #4
