Question

What is the value of x that makes L1 parallel to L2

Answer 1

Given:

Line l1 and l2 are parallel.

And having the corresopnding angles

`\begin{gathered} 8x\degree \\ (2x+60)\degree \end{gathered}`

Required:

To find the value of x.

Step-by-step explanation:

We know that if two lines are parallel, then the corresponding angles are equal.

So

`\begin{gathered} 8x\degree=(2x+60)\degree \\ \\ 8x-2x=60 \\ \\ 6x=60 \\ \\ x=(60)/(6) \\ \\ x=10 \end{gathered}`

Final Answer:

The option D is correct.

`x=10`
