SUMMARY

The discussion centers on the application of the sine law in determining unknown angles in a triangle. The user calculated an angle Θ as 68 degrees and identified a second possibility of 112 degrees. However, the textbook provided different answers: Θ = 68 degrees and Θ = 23 degrees. The consensus among participants confirms the user's calculations were correct, indicating a misunderstanding of the sine law's application in this context.

PREREQUISITES
  • Understanding of the sine law in trigonometry
  • Basic knowledge of triangle properties
  • Ability to perform angle calculations
  • Familiarity with rounding rules in mathematics
NEXT STEPS
  • Study the sine law and its applications in various triangle types
  • Learn about ambiguous cases in triangle solutions
  • Explore the concept of supplementary angles in trigonometry
  • Review rounding techniques and their implications in mathematical problems
USEFUL FOR

Students studying trigonometry, educators teaching angle calculations, and anyone seeking to clarify the application of the sine law in solving triangle problems.

So using the sine law, I found that Θ = 68 degrees. And the I found that the other possibility of Θ would be 112 degrees (180 - 68 = 112). However, the textbook says that the answers are Θ = 68 and Θ = 23. What did I do wrong?

Thanks.
