  • z+20=180(linear pair
  • z=180-20
  • z=160°

x 's measure is already given

x=20°

  • y=x+z
  • y=160+20
  • y=180°

Answer:

∡x = 20°

∡y = 160°

∠z = 160°

Explanation:

Angles on a straight line sum to 180°

⇒ ∠z + 20° = 180°

⇒ ∠z = 180° - 20°

⇒ ∠z = 160°

The central angle measure equals the corresponding arc measure.

⇒ ∡x = 20°

⇒ ∡y = ∠z = 160°
