Question

if none of the parallel lines are determined to be parallel, select
/a\ for the reason
ex: _k||n_ ∠3 = ∠6
reason # _1_
∠10 suppl. ∠4
reason

Explanation:

Step1: Analyze the relationship between angles

If two lines are parallel and cut by a transversal, then consecutive interior angles are supplementary.

Step2: Check the lines

There is no information given about the lines \(k\), \(n\), \(m\) being parallel.

Answer:

\(\angle10\) supp \(\angle4\), Reason \(N/A\)
