Answer:
Step-by-step explanation:
3x + 10??
Distribute:
(12n-12)5
60n-60 = A(n)
You can't really find what n is I don't think, because you have 2 unknown variables n and A(n).
suppose
x+122=180
x=180-122
x=58
then
x+w+33=180
58+w+33=180
w=180-91
w=89
The correct answer would be C. Hope this helps=)
