Answer:
z= 20° ( because vertically opposite angel of 20°)
y= 180° - z + 10°
y= 180° - 20° + 10°
y= 180° - 30°
y= 150° ( because linear pair)
x= 10° ( because vertically opposite angle of 10°)
x= 10° , y= 150° , z= 20°

=>Here,
x= 10°
z=20°
z= ?
Formula :
(x+y+z)=180°
2(x+y+z)=360°
=>Now,
2(10°+20°+z) =360°
20°+40°+2z =360°
2z =360°-60°
2z =300°
z =300°/2
z =150°
