A. b = 14.1, A = 24°, C = 47°
B. b = 19.9, A = 22°, C = 49°
C. b = 17, A = 26°, C = 45°

Answer 7

I know it is not C.

Answer 8

I think it is B. what do you think @ajprincess

Answer 9

Use the law of cosines and law of sines to figure this out.

Law of cosines \[b ^{2}=a ^{2}+c ^{2}-2ac \cos B\]

Law of sines\[\frac{ \sin A }{ a}=\frac{ \sin B }{ b }=\frac{ \sin C }{ c }\]

Answer 10

Well its either A or C

Answer 11

It can't be both. Plug the numbers into the law of cosine equation.
