Question

Find the value of x

Answer 1

So, here we have the following triangle:

To find x, we could use the fact that the sum of all internal angles of a triangle is always 180°. So, we could write:

`(8x+2)+60+70=180`

And now, solve this equation for x:

`\begin{gathered} 8x+132=180 \\ 8x=180-132 \\ 8x=48 \\ x=6 \end{gathered}`

Therefore, x=6
