Step-by-step explanation:
I can help you im in 7th grade and im good with math.
There are two ways to list the angles:
1) Simply name them based on the points:
∠W , ∠X , ∠Y , ∠Z
2) The way that I believe that you are supposed to list them in this case. List them as such:
∠WYZ , ∠YZX , ∠ZXW , ∠XWY

You can just do the inverse operation. 39 divied by 10 = 3.9
so 3.9 *10 =39
