Answer:
I am not sure but i think B so two solutions
We can change the law of sines a little bit to match our problem.

We know what angle Y is and what side y is, so let's use that along with angle Z and side z:

Plug in what we know:

Multiply 'z' to both sides:

Divide sin(51)/2.6 to both sides:

Plug it into your calculator.
Answer:
