Answer:
i) ∠OFE = 26°
ii) ∠EOF = 126°
Step-by-step explanation:
The sum of angles in a triangle is 180°, so ...
∠F = 180° -∠D -∠E = 180° -72° -56° = 52°
∠OFE = (1/2)∠F = 52°/2 = 26° . . . . . . OF bisects ∠F
∠EOF = 180° -∠OFE -∠OEF = 180° -26° -56°/2 = 126°
The angles of interest are ...
∠OFE = 26°
∠EOF = 126°
