Answer:

  C.  72°

Step-by-step explanation:

Angles 2 and 6 are corresponding angles, so are congruent. Their measures are the same:

  5x -48 = 3x

  2x -48 = 0 . . . . . subtract 3x

  3x -72 = 0 . . . . . multiply by 3/2

  3x = 72 . . . . . . . .add 72

(3x)° is the measure of angle 6, so the measure of angle 6 is 72°.

Answer:

72 degrees
