Answered by Ms. Sue
Why do you show lengths of two a's?

Answered by Kendall
One is <A 30 degrees and a is 9 cm
Answered by Kendall
I got obtuse for the answer
Answered by Reiny
Agree, I got angle C >90°

btw, choice 4 is rather silly,
because it is also a correct choice.
Answered by Reiny
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
