Answer
In △CED,
By angle sum property of triangle,
⇒ ∠ECD + ∠CDE + ∠DEC = 180°
⇒ 32° + 36° + ∠DEC = 180°
⇒ 68° + ∠DEC = 180°
⇒ ∠DEC = 180° - 68°
⇒ ∠DEC = 112°.
From figure,
⇒ ∠DEC + ∠AEC = 180° (Linear pair)
⇒ 112° + ∠AEC = 180°
⇒ ∠AEC = 180° - 112°
⇒ ∠AEC = 68°.
Given,
CA = CE
⇒ ∠EAC = ∠AEC = y° = 68° (Angles opposite to equal sides in a triangle are equal)
⇒ y = 68.
In △CEA,
By angle sum property of triangle,
⇒ ∠EAC + ∠AEC + ∠ECA = 180°
⇒ 68° + 68° + z° = 180°
⇒ 136° + z° = 180°
⇒ z° = 180° - 136°
⇒ z° = 44°
⇒ z = 44.
From figure,
∠BAD = ∠ADC (ALternate pair of angles between parallel lines AB and CD)
⇒ x° = 36°
⇒ x = 36.
Hence, the values of x = 36, y = 68 and z = 44.
