Answer:
138°.
Step-by-step explanation:
Extend one of the lines that forms the angle. You should get a triangle. Because the topmost and bottoms lines are straight, one of the angles has to equal 180-111, which is 69°(nice). The opposite angle to that has to also be that size. Since the topmost and bottomost lines are parallel the alternate interior angle to the 111° outside of the triangle would also equal 111°. So, because it's a straight line, the angle next to it, which is inside the triangle, is once again 69°(nice). Then, since you have 2 angles of the triangle you can add them together and subtract their sum from 180°, that should be 42°. One of the lines that 42° is on is also one x is on, so 42°+x=180°. Using this, you can find that x should be about 138°, I think.
