Question

find the value x, y, z ​

Answer 1

Answer:

y=90+30=120(exterior angle prop.)

x+90=180(linear pair)

x=90

z+30=180(linear pair)

z=150

Step-by-step explanation:

Answer 2

z = 30 - 180 (angles on the same line)

z = 150°

x = 90 - 180 (angles on the same line)

x = 90°

180 = 90+30+y (angle sum property)

180 = 120 + y

180-120 = y

60° = y
