(02.06 MC)

What is the measure of angle x?

A pair of parallel lines is cut by a transversal. An exterior angle on the left of the transversal is labeled as 40 degrees. An interior angle on the right of the transversal, which is not vertically opposite to the 40 degree angle, is labeled as x.
40 degrees
80 degrees
130 degrees
140 degrees

Answer 1

I am having a little trouble imagining this, but I am sure that this is a supplementary angle, as if it was displaced it would be equal to the adjacent angle to the 40°.  I am almost certain if I am imagining this correctly that it is 140°.  Just look at this "interior angle", if it would be the same as the angle alongside or adjacent to the exterior angle it is 140°.
