In this triangle we know: angle A = 76° angle B = 34° and c = 9 . It's easy to find angle C by using 'angles of a triangle add to 180°':. C = 180° − 76° − 34° = 70° We can now find side a by using the Law of Sines:. asin(A) = csin(C). asin(76°) = 9sin(70°). a = sin(76°) × 9sin(70°). a = 9.29 to 2 decimal places Similarly we can find side b by using the Law of …
