Step-by-step explanation:
Since x is along the entire parallelogram we will use cosine to figure out it's length.
First we do cos(40) and get cos(40)=.7660
This .7660 is equal to
or 
So we do .7660*4 and get 3.064 in for x
A is the only option with x=3.06 so it is the correct answer
I'm not for sure but I think it's ten
