Question

which angle is supplementary to ∠npi? ∠ipk ∠npl ∠mpn ∠lpm

Explanation:

Step1: Recall the definition of supplementary angles

Supplementary angles are two angles whose sum is \(180^{\circ}\).

Step2: Analyze \(\angle NPI\) and \(\angle NPL\)

We know that \(\angle NPI+\angle NPL = 180^{\circ}\) (because they form a linear - pair). A linear - pair of angles is always supplementary.

Answer:

\(\angle NPL\)
