Thank you very much This question is from textbook Precalculus
You can put this solution on YOUR website! Find the measue of the obtuse angle possibility for the triangle with the following dimensions: B= 38 degrees, b= 21, c= 25.
A)47.13 degrees
B)132.87 degrees
C)114.26 degrees
D)145.19 degrees
--------------------
Use the Law of Sines:
Sin(C)/c = Sin(B)/b
Sin(C) = 25[sin(38)/21] = 0.73293...
Therefore C = 47.13 or 180-47.13 = 132.87
------------
I think your answer is "B".
