[tex]\huge \bf༆ Answer ༄[/tex]

In the given figure, The marked angles forms a pair of co - interior angles [ because lines l and m are parallel ]

therefore,

  • [tex] \sf12x - 8 + 104 = 180[/tex]

  • [tex] \sf12x + 96 = 180[/tex]

  • [tex] \sf12x = 180 - 96[/tex]

  • [tex] \sf12x = 84[/tex]

  • [tex] \sf x = 84 \div 12[/tex]

  • [tex] \sf x = 7[/tex]

Hence, the value of x is ~ 7
