∠x + ∠z = 120°
(Exterior angle = sum of two interior opposite angles)
∠w + ∠ y = 70°
(Same property)
Total = 120° + 70° = 190°
(Exterior angle = sum of two interior opposite angles)
∠w + ∠ y = 70°
(Same property)
Total = 120° + 70° = 190°
Wrong answer
Thanks anyway

x + z is not equal to 120. Its exterior angle is 180-120= 60. Hence x +z = 60 instead of 120
