Answer:
from looking at this we can tell where z represents the other side of b
z+2x+18=180
z+2x=162
so we can see this way of doing the problem is unsolvable now we have to try elimination
16+4x-14=180
4x+2=180
4x=178
x=44.5
now to check this we have to put it on the top where it represents z
44.5+2x+18=180
62.5+2x=180
x=117.5
so that means the angle would be
2*117.5+18
253 which is a obtuse angle and the angle is not so A is not the answer
