You have to evaluate the slopes of these lines. For line AB you have a slope of
For line CD you have a slope of
Because the slopes are equal and the two lines are not one and the same, they are parallel.
X = 89
A triangle always equals 180°. Because two out of three angles are given, the two known angles (42° and 49°) can be added together which is 91°. The 91° can be subtracted from 180° to find the unknown angle x.
