Question

Hi i'm stuck on this cause u don't get what X menas

Answer 1

`x\text{ }=\text{ 21}`

Step-by-step explanation:

Here, we want to get the value of x

Mathematically, when two angles are supplementary, they add up to be 180 degrees

Thus, we have it that:

`\begin{gathered} 6(x+1)\text{ + 48 = 180} \\ 6x\text{ + 6 + 48 = 180} \\ 6x\text{ = 180-48-6} \\ 6x\text{ = 126} \\ x\text{ = }(126)/(6) \\ \\ x\text{ = 21} \end{gathered}`
