Answer:
   B.  39°, 106°, 43°
Step-by-step explanation:
The sum of angle measures in a triangle is 180°. Then the sum of angle expressions will be 180.
   (3x +1) +(11x -4) +(5x -7) = 180
   19x -10 = 180 . . . . . collect terms
   19x = 190 . . . . . . . . add 10
   x = 10 . . . . . . . . . . . divide by 19
__
Then the three angle measures are ...
- 3·10 +1 = 31
- 11·10 -4 = 106
- 5·10 -7 = 43
The appropriate choice is ...
   B.  31°, 106°, 43°
