Answer 2

B

Explanation:

The equation to solve is:

`Sin(33)=(7)/(x)`

Sin 33 has a value in the calculator. We simply cross multiply and do algebra and solve:

`Sin(33)=(7)/(x)\\Sin(33)*x=7\\x=(7)/(Sin(33))\\x=12.85`

Rounding to 1 decimal place, we have:

12.85 = 12.9

Answer choice B is right.
