Answer:
Supplementary
Step-by-step explanation:
Since the two angles add up to 180 degrees, they are supplementary
1. x - 8= 47
47 + 8 = 55
55 = x
2. 7x = 28
28 divided by 7 = 4
x = 4
3. 6x - 5 = 31
31 + 5 = 36
36 divided by 6 = 6
x = 6
4. x + 4 = 12
12 - 4 = 8
x = 8
X = 14, y = 6, and z is about 17.3.
