find the value of unknown angles

Answer:
x = 75 degree , y = 75 degree , z = 105 degree
Step-by-step explanation:
x = 75 degree (being corresponding angles)
x=y (being corresponding angles)
75 = y
substituting the value
y + 30
75 + 30
105 degree
z = y + 30 (being corresponding angles)
z = 105 degree
