Answer:

  • 235°

Step-by-step explanation:

Given

  • AB ║ CD
  • m∠BCD = 52°  
  • m∠EAB = 73°

To find

  • m∠ABC = ?

Solution

Imagine line BF parallel  to both AB and CD

Then

  • m∠ABC = m∠ABF + m∠CBF
  • m∠ABC =  (180° - m∠EAB) + (180° - m∠BCD)
  • m∠ABC = (180° - 73°) + (180° - 52°) = 107° + 128° = 235°
