This trig problem is related to a classic geometry topic, the “Angle-Side-Side” (false) triangle congruency theorem. In other words, when given A, b and a, there may be 0, 1 or 2 solutions. The fallacy of “ASS” is easy to show with a straightedge and compass. In Regents geometry, this always came after SSS, SAS, ASA, AAS, etc.
