The Solution.

Step 1:

We shall find the third angle in the triangle.

$\begin{gathered} \angle C=180-(64+85)\text{ ( sum of angles in a triangle)} \\ \angle C=180-149=31^o \end{gathered}$

Step 2:

we shall determine the proportion to find side b by applying the Sine Rule.

$(\sin 31^o)/(9.3)=(\sin 85^o)/(b)$
