Answer:
∠ADG - ∠MDF = 14°
Step-by-step explanation:
in Parallelogram opposite angles are equal
and sum of adjacent angle = 180°
=> ∠ABC + ∠BCF = 180°
=> ∠ABD + ∠DBC + 52° = 180°
=> ∠ABD + 90° = 128°
=> ∠ABD = 38°
∠DAB = ∠DAF + ∠FAB
=> ∠DAB = 56° + 52°
=> ∠DAB = 108°
in ΔABD
∠ADB + ∠DAB + ∠ABD = 180°
=> ∠ADB + 108° + 38° = 180°
=> ∠ADB = 34°
∠ADG = ∠ADB = 34°
∠CED = 180° - ∠BED
=> ∠CED = 180° - 72°
=> ∠CED = 108°
in ΔCDE
=> ∠CED + ∠ECD + ∠EDC = 180°
=> 108° + 52° + ∠EDC = 180°
=> ∠EDC = 20°
∠MDF = ∠EDC = 20°
∠ADG - ∠MDF = 34° - 20°
=> ∠ADG - ∠MDF = 14°
