## Trigonometry (11th Edition) Clone

We can use the law of sines to find the angle $C$: $\frac{b}{sin~B} = \frac{c}{sin~C}$ $sin~C = \frac{c~sin~B}{b}$ $sin~C = \frac{(145~m)~sin~(72.2^{\circ})}{78.3~m}$ $sin~C = 1.763$ Since there is no angle C such that $sin~C \gt 1$, the angle C is not defined. We can not construct a triangle with the values given in this question.
