A. 120
B. 360
C. 77
D. 17

Answer:

  D.  17

Step-by-step explanation:

The sum of the exterior angles of a polygon is 360°.

  x° +2x° +120° +3x° +18° +120° = 360°

  6x +258 = 360 . . . . . . . collect terms, divide by °

  6x = 102 . . . . . . . . . subtract 258

  x = 17 . . . . . . . . divide by 6
