Well you can start by drawing a triangle with the information
the size of angle B can be found using the Law of Sine
[tex] \frac{sin(150)}{9.4)} = \frac{sin(B)}{4.8} [/tex]
the size of angle C can be found using angle sum of a triangle.
The length of side c can be found using the Law of Cosines
[tex]c^2 = 4.8^2 + 9.4^2 - 2 \times4.8\times9.4\times cos(C)[/tex]
hope it helps
