Answer:
∠ MLN = 21°
Step-by-step explanation:
See the attached diagram.
We are given that ∠ OLN = 31° and ∠ MLO = 52°.
So, the diagram is like that OL is the baseline of both the angles and two different lines one LM and the other LN are drawn from point L such that two angles will form and the measurement of ∠ OLM = 52° and ∠ OLN = 31°.
So, there will another angle form which is ∠ MLN which measures (52 - 31) = 21° (Answer)
