Question

In the diagram, how many angles are supplementary but not adjacent angles with angle 7?

Answer 1

The answer is zero.

If any of the pairs of lines were parallel, there would be some same-side interior angles or such that would be supplementary.  However, since the lines are not parallel lines crossed by a transversal, the only ones guaranteed to be supplementary to angle 7 are the ones adjacent to it that form a linear pair.
