WebUse the Law of Sines, sinC/c = sinB/b, to find angle A: sin (C) / 7.4 = sin (104.1°) / 15.2 sin (C) = 7.4 × sin (104.1°) / 15.2 sin (C) = 0.4722... C = 28.2° to one decimal place Find angle A using "angles of a triangle add to 180": A = 180° − (104.1° + 28.2°) A = 180° − 132.3° A = 47.7° to one decimal place So A = 47.7°, B = 104.1°, and C = 28.2°
