Answer:
x = 2
Step-by-step explanation:
It is the picture of parallelogram . And in a parallelogram , vertex angles which are opposite to each other are equal. So, angleA = angleC and angleB = angleD.
As angleA = angleC ,
[tex]6x + 4 = 2x + 12[/tex]
[tex] = > 6x - 2x = 12 - 4[/tex]
[tex] = > 4x = 8[/tex]
[tex] = > x = \frac{8}{4} = 2[/tex]
