Determine Whether the Law of Sines or the Law of Cosines

Multiple Choice

Determine whether the Law of Sines or the Law of Cosines is needed to solve the tri- angle. Then solve the triangle. $$a = 17 , b = 19 , C = 60 ^ { \circ }$$

A) Law of Sines; $A \approx 60 ^ { \circ } , B \approx 54.5 ^ { \circ } , c \approx 19$
B) Law of Sines; $A \approx 54.5 ^ { \circ } , B \approx 60 ^ { \circ } , c \approx 19$
C) Law of Cosine; $A \approx 54.5 ^ { \circ } , B \approx 65.5 ^ { \circ } , c \approx 18.08$
D) Law of Sines; No solution
E) Law of Cosine; No solution
