## Trigonometry (11th Edition) Clone

If we are given a, A, and C in triangle ABC, then we can use the law of sines to find side c. Since the value of side c has one possible value, this case is not ambiguous. Angle B also has one possible value since $A+B+C = 180^{\circ}$. Then we can use the law of sines to find side b. Since the value of side b has one possible value, this case is not ambiguous.
