What is thw value of x?
x=_

x = 30

Step-by-step explanation:

The 2 given angles are same- side exterior angles. That is they are on the same side of the transversal and outside the parallel lines.

same- side exterior angles are supplementary, thus

x + 12 + 3x + 48 = 180, that is

4x + 60 = 180 ( subtract 60 from both sides )

4x = 120 ( divide both sides by 4 )

x = 30
