Answer:
Step-by-step explanation:
1. AB||DC and AB = CD Given
2. ∠1 = ∠4 If lines are parallel, then alternate interior
angles are equal.
3 .AC = AC Reflexive
4. ΔABC ≅ ΔCDA SAS
5. ∠2 = ∠3 CPCTE
7x + 5 = 2x - 35
=> 7x - 2x = - 35 - 5
=> x( 7 - 2 ) = - ( 35 + 5 )
=> x( 5 ) = - ( 40 )
=> x × 5 = - 40

x = 5
Therefore the value of x in the given equation 5
