hello
from the question given, we know we have to use trigonometric ratio and in this case, find the sine angle of the given angle
[tex]\sin \theta=\frac{opposite}{hypothenus}[/tex][tex]\begin{gathered} \text{opposite}=8.5 \\ \theta=32 \\ \text{hypothenus}=x \end{gathered}[/tex]
we can insert this values into the previous equation
[tex]\sin 32=\frac{8.5}{x}[/tex]
from the calculations above, option A is the right answer
