in Δ DCB -
∠DBC+∠BCD+∠CDB=180°(ANGLE SUM PROPERTY)
⇒95°+55°+∠CDB=180°
⇒∠CDB=30°
NOW,
∠DAE+∠DEA=∠EDC+∠CDB (EXTERIOR ANGLE PROPERTY)
⇒ x+35° = 20°+30°
⇒x=15°
∠DBC+∠BCD+∠CDB=180°(ANGLE SUM PROPERTY)
⇒95°+55°+∠CDB=180°
⇒∠CDB=30°
NOW,
∠DAE+∠DEA=∠EDC+∠CDB (EXTERIOR ANGLE PROPERTY)
⇒ x+35° = 20°+30°
⇒x=15°
sorry for late answer.
