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
