Question

if AB is parallel to CD then,find x,y,z...?​

Answer 1

Answer:

x = 20; y = 60; z = 120

Step-by-step explanation:

AB||CD

3x = y Alternate Angles

z = 180 - 3x Co-int angles

y+80+2x = 180 angles of triangle

Sub in y=3x

3x+80+2x=180

5x=100

x=20

Sub in x=20 where applicable

y = 3(20) = 60

z = 180 - 3(20) = 120

Answer 2

Answer:

• x=20
• y=60
• z=40

Step-by-step explanation:

• C=80
• 180-80=3x+2x
• 100=5x
• x=20
• 3x=60
• 2x=40
• in triangle
• 80+40+y=180
• 180-120=y
• 60=y
• 80+60+z=180
• 180-140=z
• 40=z
