First find an expression for an angle that forms linear pairs with (6x-6).
x=9
To find the value of x, we have to relate the two angles somehow. To do that, we will first determine an expression for the angle that forms a linear pair with (6x-6)^(∘). Linear pairs are supplementary so the other angle can be written as 180^(∘)-(6x-6)^(∘).
