SUMMARY
The discussion revolves around solving a trigonometric problem involving triangle ABC, where AC = 3AB and angle BAC = 120°. Participants suggest using the sine rule to find the unknown angle BCA (θ). The correct application of the sine rule is established as a/sin(α) = b/sin(β) = c/sin(γ), with specific angles and sides defined. The conversation emphasizes the importance of correctly labeling angles and sides to avoid confusion in calculations.
