Answer:

The answer is A.

Step-by-step explanation:

We know two sides, and one angle of the corresponding side. Thus, we can use the Law of Sines to find the last angle.

The Law of Sines:

[tex]\frac{sin(A)}{A}=\frac{sin(B)}{B}= \frac{sin(C)}{C}[/tex]

Plug in what we know:

[tex]\frac{sin(38)}{70} =\frac{sin(C)}{108}[/tex]

Cross multiply:

[tex]70sin(C)=108sin(38)[/tex]

[tex]sin(C)=\frac{108sin(38)}{70}[/tex]

[tex]C=arcsin(\frac{54sin(38)}{35} )[/tex]

[tex]C \approx 71.7827[/tex]
