In my opinion the answer it either A or C because they make the most sense if you calculate.
Find the supplement to the left of 115.
Because line b and c are parallel, the supplement will be a corresponding angle with (5x+5).
5 multiplied by 12 is 60
60+5 is 65. Which was the supplement of 115. Therefore the answer is
B. x=12
