Answer:
[tex]\boxed{\sf C. \ 6.6 \ units}[/tex]
Step-by-step explanation:
The triangle is a right triangle.
We can use trigonometric functions to solve.
[tex]\sf cos(\theta)=\frac{adjacent}{hypotenuse}[/tex]
[tex]\sf cos(35)=\frac{MO}{8}[/tex]
[tex]\sf 8 \ cos(35)=MO[/tex]
[tex]\sf 6.55321635...=MO[/tex]
