I assume it's 22.

1. Option B. (Parallel lines with a line crossed through it.)
2. C. - x=14, y=12
3. C. - Alternate exterior angles
4. C. - A line perpendicular to a given line through a point not on the line.
5. B. - 18
6. B. - m<1=m<8
7. B. - 68 degrees
8. C. - <2 and <7
9. (Short essay) Opposite angles formed by two intersecting lines are equal, so angle 1 is the same as angle 4. This means that angle 1 = angle 5. If r and s are parallel, then the angles formed when l intersects r are the same s the angles formed when l intersects s. Angle 1 = Angle 5, Angle 2 = Angle 6. Angle 1 = angle 5, so r and s are parallel.
10. (short essay) 1. <1 and <5 are supplementary. 1. Given 2. Vertical angles are congruent 3. Substitution. 4. L || M 4. Consecutive Interior Angles Theorem.
11. (Short Essay) B is wrong because they are not supplementary. They a alternate interior angels so they are equal.
