Answer:
z = 145° , y = 35° , x = 145°
Step-by-step explanation:
z = 180° - 35° = 145° (angles in a straight line add up to 180° i.e z + 35° 180°)
y + z = 180° (angles in a straight line add up to 180°)
∴ y = 180° - 145° = 35°
Alternatively: y = 35° (vertically opposite angles are equal)
x = z = 145° since vertically opposite angles are equal.
