In each diagram, line k is parallel to line j, and line t intersects lines k and j.

Based on the diagrams, which statement is true?

• The value of x is 79, because the two angles shown in each diagram are congruent.

• The value of x is 101, because the two angles shown in each diagram are supplementary.

• The value of x is greater than 90, because the two angles shown in each diagram are obtuse angles.

• The value of x is 11, because the two angles shown in each diagram are complementary.

Four triangles are shown.

Based on these triangles, which statement is true?

• w = 75°, because 45 + 60 = 105 and 180 - 105 = 75

• w = 105°, because 180 - (45 + 60) = 75 and 180 - 75 = 105

• w = 285°, because 45 + 60 = 105 and 105 + 180 = 285

• w = 165°, because 180 - 60 = 120 and 120

  + 45 = 165
