Important Note Regarding Parallelograms:

Consecutive angles in a parallelogram are supplementary.

From 1:

Angle D = 55.
Then angle A and C is 125 and Similarly Angle B is 55.
Sufficient.

From 2:

No extra info.
Insufficient.

Question stem:- what is the measure of angle ABC?

Note:- Opposite angels of a parallelogram are congruent (D = B, A = C).

As per note, $$\angle{ADC}=\angle{ABC}=55°$$
Sufficient.

St2:- The sum of angles ABC and BCD is 180°

Note:- Consecutive angles of a parallelogram are supplementary (B + C =180°, A + D = 180° )
St2 is nothing but the property of angles of the parallelogram.
Insufficient.

Ans. (A)

Angle ABC = Angle ADC = 55 ( Opposite angle of a parallelogram )
Sufficient

(2) The sum of angles ABC and BCD is 180°.
No new information
Insufficient

Hence, A.
