Solve triangle ABC if ZA = a = 48.8°, b = 8.5 cm, and c = 15.1 cm. Using the Law of Cosines, cm. Your answer should accurate to 2 decimal places. Using the Law of Cosines again, CosZB = Cos 3 2 Your answer should accurate to 5 decimal places. Thus, B 2 Your answer should accurate to 2 decimal places. cosZC = COS y A Your answer should accurate to 5 decimal places. Thus, y 2 Your answer should accurate to 2 decimal places. Check by seeing if the total of the three angles is 180°.
