Answer 1

Answer:

z=150 degree

x=90degree

y=110

Step-by-step explanation:

Answer 2

Answer:

x = 90°

y= 120°

z= 150°

Step-by-step explanation:

z+30°=180(angle sum prop. of straight line)

so, z= 150°

x+90°=180°

so, x=90°

And z= 90 + angle unknown (Ext. angle sum prop.)

so, unknown angle = 60°

therefore y=120°
