Explanation:

Step1: Identify vertex and rays

The angle has vertex N, with rays NM and NL (or NM and NK? Wait, the marked angle is between NM and NL? Wait, the diagram: N is vertex, NM is horizontal right, NL is going down-right, NK is vertical down. Wait, the marked angle is between NM and NL? Wait, no, the angle at N between NM (right) and NL (down-right), or between NM and NK? Wait, the diagram: the angle is marked at N between NM (horizontal) and NL (the other ray). Wait, also, angles can be named by vertex, or by three points (with vertex in middle).

Step2: Name using three points

First way: using three points, with vertex N. So the angle is ∠MNL (since the sides are NM and NL, vertex N). Second way: using the vertex alone, ∠N (since there's only one angle at N? Wait, no, if there are multiple angles at N, but here the marked angle is between NM and NL. Wait, or maybe between NM and NL, and also, since N is the vertex, another way is ∠N. Wait, but let's check: the angle is formed by rays NM and NL, so first name: ∠MNL (three points, M-N-L), second name: ∠N (vertex). Wait, but maybe also, if the other ray is NK, no, the marked angle is between NM and NL. Wait, the diagram: N is top, M is right on NM, L is on the other ray, K is on vertical down. So the marked angle is between NM (right) and NL (the ray going to L). So two ways: ∠MNL (using three points, with N in middle) and ∠N (using vertex, since it's the only angle at N? Wait, no, there's also angle between NK and NL, but the marked one is between NM and NL. So first: ∠MNL, second: ∠N (but maybe also, if we consider the vertex and the two sides, but usually, angle can be named by vertex (if unique) or by three points. So:

First angle: ∠MNL (points M, N, L, with N as vertex)
Second angle: ∠N (vertex N, since the marked angle is at N between NM and NL, and if there's no ambiguity, we can name it ∠N)

Wait, but maybe the other way: ∠LNM (same as ∠MNL, just reversed order of M and L). But the problem says two different ways. So:

First: ∠MNL
Second: ∠N

Or maybe, if the angle is between NM and NL, then another way is ∠N (vertex) and ∠MNL (three points).

Answer:

$\angle MNL$ ; $\angle N$
