Explanation:
This is a law of sines problem.
Law of sines states that
A / sin (a) = B(sin b) = C (sin c)
5 / sin (60) = 9 / sin (x)
Simplifying this equation gives us sin (x) = (9 * sin (60)) / 5. Now we take the arc sin of both sides, to get that x = arc sin ((9 * sin (60)) / 5). Plugging this into a calculator gives us..... no solutions
I think thats the right solution as I plugged it into a law of sines calculator as well.
