Answer:

y=20 degrees

Step-by-step explanation:

  1. if AB // CD then take BD as transversal line
  2. so that angle ABD=y+2y+y=4y
  3. as per the theorem.... the sum of opposite interior angles is equal to 180 degrees
  4. angle ABD+angleCDB=180 degrees
  5. so 4y+5y=180degrees
  6. 9y=180degrees
  7. y=180/9
  8. y=20 degrees
