In 1st co-interior angles given are 126&44
In parallel lines joined by a transversal, the sum of angles is always 180° But sum of 126+44 =170°
In 2nd question in line m, x=105° (linear pair)
But 105 is not =75°(alternate angles of parallel lines are equal)
In 3rd vertically opposite angle of 57°=57°
On line m, 180°-123°=57°
So your answer is option 3rd
