Step-by-step explanation:
Since, in ΔABC:
∠A+∠B+∠C=180°
⟹∠A=180°−55°−65°=60°.
Now, AN is angle bisector of ∠A then,
∠CAN=∠BAN=30°
Now, ∠ANM=∠NCA+∠CAN=55°+30°=85°........(Sum of two interior angles is equal to opposite exterior angle).
Now, in ΔANM:
∠AMN=90° and
∠MAN+∠ANM+∠AMN=180°
⟹∠MAN=180°−90°−85°=5°
