Answer: C) x = 17; 52 degrees
-----------------------------------------------------
Erase line A. For the pair of lines B and C, the marked angles are same side exterior angles. They are supplementary
(2x+18) + (6x+26) = 180
8x + 44 = 180
8x = 180-44
8x = 136
x = 136/8
x = 17
Since x = 17,
smaller angle = 2x+18
smaller angle = 2*17+18
smaller angle = 34+18
smaller angle = 52 degrees
