34. ANS:
[4] Because the three interior angles of a triangle have measures with sum 180, w + 31 +
90 = 180, so w = 59. Because vertical angles are congruent, y = 59. Because
supplementary angles have measures with sum 180, x = v = 121.
Because the three interior angles of a triangle have measures with sum 180, z + 68 +
y = z + 68 + 59 = 180, so z = 53.
[3] small error leading to one incorrect answer
[2] three correct answers, work shown
[1] two correct answers, work shown
35. ANS:
Lines j and k are perpendicular. It is given that line k is parallel to line l and line j is perpendicular to line l
Therefore, line j is perpendicular to k, because in a plane, if a line is perpendicular to one of two parallel lines,
then it is also perpendicular to the other.
36. ANS:

 ; Line r is perpendicular to line p because a line perpendicular to one of two parallel lines is also
9
perpendicular to the other. Thus, the slope of line r is the opposite reciprocal of the slope of line p.
