Question

Given m n, find the value of x. f (8x-7) (x-160° Answer:

Answer 1

As m is parallel to n, the angles (8x-7) and (x+16) are supplementary (they add 180 degrees).

Then, we can write:

`\begin{gathered} (8x-7)+(x+16)=180 \\ 8x+x-7+16=180 \\ 9x+9=180 \\ 9x=180-9 \\ 9x=171 \\ x=(171)/(9) \\ x=19 \end{gathered}`

The value of x is 19.
