Answer:
x = 43
Explanation:
since the line is parallel, there are a few relationships that goes on in between the parallel lines with the angles formed by the third line (the third line is known as a transversal)
the two angles shown are same side interior angles because they are on the same side of the transversal and on the inside of the parallel lines
same side interior angles always add up to 180 since, if you put them together, they would form a straight angle
so we can set the equation to x + 27 + x + 67 = 180
add like terms: 2x + 94 = 180
subtract 94 from 180: 2x = 86
divide both sides by 2: x = 43
