Answer:

i)

  • x = 50°, alternate interior angles
  • z = 60°, corresponding angles
  • y = 180° - (50° + 60°) = 70°, straight angle is 180°

ii)

  • b = 180° - 152° = 28°, consecutive interior angles
  • a + b = 58° ⇒ a = 58° - 28° = 30°, alternate interior angles

iii)

Imagine parallel line through vertex of angle x.

  • x = 36° + 28° = 64°

iv)

Same as above:

  • x = 360 - (45° + 35°) = 280°
