Answer:

A

Step-by-step explanation:

[tex]\frac{sin A}{a} = \frac{sin B}{b} = \frac{sin C}{c}[/tex]

Also, you need to subtract the 2 known angles from 180 to find the missing angle measurement. 180 - 85 - 64 = 31

The angles go with the side lengths opposite them.

[tex]\frac{sin 64}{a} = \frac{sin 85}{b} = \frac{sin 31}{9.3}[/tex]
