x = 70

Answer:

  C. 78°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

  (7x-6)° +(4x+11)° +43° = 180°

  11x +48 = 180 . . . . . divide by °, simplify

  11x = 132 . . . . . . . subtract 48

  x = 12 . . . . . . . divide by 11

Then the measure of angle T is ...

  ∠T = (7x -6)° = (7(12) -6)°

  ∠T = 78°
