Answer:

first option

Step-by-step explanation:

In a parallelogram consecutive angle are supplementary, sum to 180, so

2a + 122 = 180 ( subtract 122 from both sides )

2a = 58 ( divide both sides by 2 )

a = 29

---------------

In a parallelogram the opposite sides are congruent, then

b + 6 = 10 ( subtract 6 from both sides )

b = 4
