Answer 2

Answer:

x=90;' y=140; z=40

Step-by-step explanation:

x-50+x+50 = 180   (angles on a straight line)

2x = 180

x = 180/2

x = 90

now,

x+50+z = 180   (angles on a straight line)

90+50+z = 180      (since  x=90)

z = 40

now,

y + z = 180   (angles on a straight line)

y + 40 = 180    (since z = 40)

y = 140

Therefore, x=90; y=140; z=40
