Answer:
D. 104
Step-by-step explanation:
We know that xy and yz are supplementary to each other
That means they add up to 180
We can set up an equation with this information
(4x+32)+(2x+40)=180
6x+72=180
6x=108
x=18
Now that we know what x is, we can plug it into 4x+32 to find degree of xy
4(18)+32
72+32
D. 104
