## Trigonometry (11th Edition) Clone

We can use the law of sines to find the angle $B$: $\frac{c}{sin~C} = \frac{b}{sin~B}$ $sin~B = \frac{b~sin~C}{c}$ $sin~B = \frac{(386~cm)~sin~(68.5^{\circ})}{258~cm}$ $sin~B = 1.39$ Since there is no angle B such that $sin~B \gt 1$, the angle B is not defined. We can not construct a triangle with the values given in this question.
