We can draw a perpendicular line through the two parallel lines to create a pentagon (there is an image attached in case you need to see where the line intersects the two parallel lines). Since the angle sum of a pentagon is $540^{\circ}$ , we can solve for $x$ .

$x+140+138+90+90 = 540$ (Angle sum of pentagon is $540^{\circ}$ )

$x+458=540$ (collect like-terms)

$x=82^{\circ}$

Hope this helps :)
