A.) 7

Step-by-step explanation:

If we know that angle 6 = angle x - 3 , and angle 12 = angle x + 1, and that 12 is twice as much as six. We can conclude 7 has the be the answer because that would make x - 3 = 4 if x = 7 and x + 1 = 8 if x = 7 as well. That would fit the criteria that angle 8 is also twice as much as 4, so 7 should be the answer !
