In the given figure,

Angle 108° + 12x = 180°

because they for pair of co- interior angles which are supplementary.

so,

  • [tex]12x + 108\degree = 180\degree[/tex]

  • [tex]12x = 180\degree - 108\degree[/tex]

  • [tex]12x = 72\degree[/tex]

  • [tex]x = \dfrac{72\degree}{12} [/tex]

  • [tex]x = 6\degree[/tex]

hence , value of x = 6°

Answer:

[tex]12x + 108 = 180 \\ \\ 12x = 180 - 108 \\ \\ 12x = 72 \\ \\ x = \frac{72}{12} \\ \\ x = 6[/tex]

it's is a co - inter angle they sum are 180
