Answer: A=28.1, B = 61.9
Step-by-step explanation:
Use the law of sines, [tex]\frac{SinC}{c} =\frac{SinB}{b}[/tex], to solve for B, [tex]arcsin(\frac{bSinC}{c})= B[/tex], and plug in your numbers [tex]arcsin(\frac{(60)Sin(90)}{(68)})= B[/tex], and you get B = 61.9. Then, you use the fact that angles in a triangle to solve for A, which gives 28.1.
