Answer:
X= 100° , Y= 150° , Z= 30°
X+ 30 +50 = 180° ( forming a straight line)
X+ 80= 180
X= 180-80
X= 100°
Z= 30 ° (opposite angles are equal)
Y+z= 180° ( forming a straight line)
Y+30= 180
y= 180-30
y= 150 °

z = 30 /vertically opposite angles
now
x + z + 50 = 180 /linear pair axiom
x + 30 + 50= 180
x = 180 -80
x = 100
similarly
30 + y = 180 /LPA
y = 180 -30
y = 150
conclusion :-
x = 100
y = 150
z = 30
keep asking
