I am not entirely sure what your asking but i think you mean which will coast the least and that would be 8 since it’s the smallest amount
Y-9 + y/2 = 180
Add nine to each side
y+y/2=189
Multiply each side by two
2y+y=378
Add the y's together
3y=378
Divide it all by three
y=126
so, Angle B is 126 degrees
I hope that helps!
