Solve triangle knowing A = 37, a = 49 and b = 54
Ans: 2 solutions,
Explanation:
Find angle B by the Law of Sine:
Two possible solutions.
sin x = 0.66 -->
These 2 arcs (angles) have the same sin value (0.66).
The right answer is 41^@55. The angle B = 138.45 would require a side b larger than b = 54.
