I tried solving this like I was taught but it didn't get any of the answer options

For the given right angle triangle:
Hypotenuse = x
The adjacent side to the angle 35 = 9
So,
[tex]\begin{gathered} \cos 35=\frac{adjacent}{hypotenuse} \\ \\ \cos 35=\frac{9}{x} \\ \\ x=\frac{9}{\cos 35}=10.987 \end{gathered}[/tex]Rounding to the nearest tenth
So, the answer will be x = 11
