In triangle ABC, m Imported Asset A = 40°, m Imported Asset B = 80°, m Imported Asset C = 60°, and side AB = 12. Find sides AC and BC.

In triangle ABC,  A = 40°,  B = 80°,  C = 60°, and side AB = 12. Find sides AC and BC.

12/sin 60  =  AC/sin 80

AC  = 12*sin 80/sin 60 ≈  13.646

12/sin 60 = BC / sin 40

BC = 12*sin(40)/sin(60) ≈  8.907
