By question it's given that m || n . So here we can use the properties of parallel lines . One of them which we will use here is ,
- corresponding angles are equal .
Here the two given angles are corresponding angles hence they will be equal. We create them in order to find the value of x.
[tex]\sf\implies 68^o = 6x + 8^o \\\\\\\sf\implies6x = 68^o - 8^o\\\\\sf\implies 6x = 60^o \\\\\\\sf\implies x = 60^o/6 \\\\\\\sf\implies \boxed{\red{ \sf x = 10^o }}[/tex]
Hence the value of x is 10° .
