Answer:
12° and 168°
Step-by-step explanation:
If x is the angle, and y is the supplementary angle, then:
x + y = 180
x = y − 156
Solve the system of equations using substitution:
y − 156 + y = 180
2y = 336
y = 168
Plug back into either equation to find x:
x = 12
Answer:
subtract 2 from both sides
Step-by-step explanation:
if you subtract 2 from both sides you will get k=3
It is the third option: {1, 2, 3}
1,248 divided by 4= 312
