B. 31°, 43°, 106°
since all angles of a triangle add up to 180°, you combine all of the equations to equal 180 and solve for X. the equation you would get it 3x+1+11x-4+5x-7=180. this simplifies to 19x-10=180. then you solve for x, and it is 10. then, you plug 10 into all of the equations separately to find the angles. therefore, the answer is B

If the winner has 308 votes, if you add on 40 votes so it makes the total votes to be twice the amount of the other, this is 348. Then you can divide by two to get the amount of votes.
348 / 2 = 174 votes.
Hope this helps!
