The correct answer (180) isn't given in the choices.

The only thing that could conceivably make sense is that they put the z in the wrong place in relation to the line and it should be on the acute angle either beside or below where it is in the picture. In which case the answer would be E. 110 degrees.

They failed horribly. Of course it's 180.
