Multiple Choice

Determine whether the Law of Sines or the Law of Cosines is needed to solve the tri- angle. Then solve the triangle. Round your answer to two decimal places.
a=154,B=10,C=5a = 154 , B = 10 ^ { \circ } , C = 5 ^ { \circ }


A) Law of Cosines; No solution
B) Law of Sines; A=165,b51.86,c103.32A = 165 ^ { \circ } , b \approx 51.86 , c \approx 103.32
C) Law of Sines; A=165,b103.32,c51.86A = 165 ^ { \circ } , b \approx 103.32 , c \approx 51.86
D) Law of Cosines; A=165,b103.32,c51.86A = 165 ^ { \circ } , b \approx 103.32 , c \approx 51.86
