Assume a triangle ABC has standard labeling. Determine whether SAA, ASA, SSA, SAS, or SSS is given. Then decide
whether the law of sines or the law of cosines should be used to begin solving the triangle.
-a, c, and B
A) SAS; law of sines
B) SSA; law of sines
C) SAS; law of cosines
D) SSA; law of cosines

Given sides a and c, and angle B, this forms a SAS (Side-Angle-Side) situation because we have two sides and the angle between them given. The law of cosines is appropriate to use first in this case to find the unknown side or angles.
