Your correct answer is c.
Answer:
Sorry I am a little confused about the answer
Step-by-step explanation:
The value of b will be 43° as it is vertically opposite angle.. !!
Add the three angles and set them to 180
4x-13+15+x+18=180
5x+20=180
5x=160
x=32
Then plug in to get A and C
A=4*32-13
A=115
C=32+18
C=50
I believe the answer you are looking for is 2.
