I cannot understand how i get a negative answer. I have a triangle with three angles and one side. To get another side $c$ I used the below calculation but got a negative answer.
Given that $\frac{c}{\sin C} = \frac{b}{\sin B}$ and the following calculation is made: $c= \frac{10\times\sin 90}{\sin 68.47}$ or $c= (10\times 0.894)/ -0.60123$ I get a negative answer for $c$?
