Answer:
B
Step-by-step explanation:
The equation to solve is:
[tex]Sin(33)=\frac{7}{x}[/tex]
Sin 33 has a value in the calculator. We simply cross multiply and do algebra and solve:
[tex]Sin(33)=\frac{7}{x}\\Sin(33)*x=7\\x=\frac{7}{Sin(33)}\\x=12.85[/tex]
Rounding to 1 decimal place, we have:
12.85 = 12.9
Answer choice B is right.
