Either or can be used with any triangle...I personally find the law of sines is often more compact as in this case we can just say;
(sin115)/18=(sin40)/c (with no need for b or B as would be needed with the law of cosines...)
c=18(sin40)/(sin115)
c≈12.77

Step-by-step explanation:
By graphing it, oddly enough... you can just make a table of values and graph that, bear in mind that a LINEAR function is just a LINE, and to graph a line, all you need is two points. *Unless you have a specific function in mind.
