Question
![Assume Za is opposite side a, ZB is opposite side b, and Zy is opposite side c.
Solve triangle ABC if ZA = a = 49.7°, b = 12.1 cm, and c
15.5 cm.
Using the Law of Cosines,
cm.
Your answer should accurate to 2 decimal places.
Using the Law of Cosines again,
COSZB =
cos B 2
Your answer should accurate to 5 decimal places.
Thus, B
Your answer should accurate to 2 decimal places.
COSZC = cos y 2
Your answer should accurate to 5 decimal places.
Thus, y
Your answer should accurate to 2 decimal places.
