Use the given information to solve the triangle for A = 150°, b = 4.8, a = 9.4
ELEN [110]
Well you can start by drawing a triangle with the information 

the size of angle B can be found using the Law of Sine

\frac{sin(150)}{9.4)}  =  \frac{sin(B)}{4.8}

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

c^2 = 4.8^2 + 9.4^2 - 2 \times4.8\times9.4\times  cos(C)

hope it helps
