Let ∠CAB = x,
∴ ∠ACD = x (Alternate ∠S)
In ∆ACD,
∠D = 180° – (30° + x)
= 150° – x
∵ ABCD is a cyclic quadrilateral.
∴ ∠D + ∠B = 180°
⇒ 150° – x + 65° = 180°
⇒ x = 35°
∴ ∠ACD = x (Alternate ∠S)
In ∆ACD,
∠D = 180° – (30° + x)
= 150° – x
∵ ABCD is a cyclic quadrilateral.
∴ ∠D + ∠B = 180°
⇒ 150° – x + 65° = 180°
⇒ x = 35°
