Solution :
★ ∠ABC + ∠BAC = ∠ACD
( Sum of two interior angle is equal to one exterior angle )
→ 30° + 50° = x
→ x = 70°
★ ∠ACD + ∠ADC + ∠CAD = 180°
( Sum of angle in ∆ )
→ 70° + 45° + ∠CAD = 180°
→ ∠CAD + 115° = 180°
→ ∠CAD = 180° - 115°
→ ∠CAD = 65°
★ ∠EAD + ∠BAC + ∠CAD = 180° ( L.P.A )
→ y + 50° + 65° = 180°
→ y + 115° = 180°
→ y = 180° - 115°
→ y = 65°
∴ x = 70° and y = 65°
