In the diagram shown, line m is parallel to line n. Roscoe says
that 22 and 25 are supplementary angles. Is he correct? Why
or why not?

Yes, because 26 is supplementary to
25, and 22 and 26 are congruent
corresponding angles.
Yes, because 22 is obtuse and 25 is
acute.
No, because 22 and 23 are
supplementary, so 22 cannot be
supplementary to <5.
No, because 22 and 25 are not a
linear pair of angles.
