4x+2x=180( cointerior angles)
6x=180
x=180÷6
x= 30
6x=180
x=180÷6
x= 30

Given a // b , l is the transversal.
p = 2x [ vertically opposite angles ]
4x + p = 180°
[ sum of interior angles same side
if the transversal are supplementary ]
4x + 2x = 180°
=> 6x = 180°
=> x = 180°/6
x = 30°
Therefore ,
Option ( D ) is correct.
