Answer:
Given that: ABCD is a cyclic quadrilateral
∠DCB=82°
∠DCA=46°
∠CYB=62°
∠ACB=∠DCB−∠DCA=82−46=36°
Consider △CYB
∠CBY=180°−∠BCY−∠CYB=180°−62°−36°=82° (sum of three angles of a triangle is 180°)
Also, ∠ACD=∠ABD=46° ......... (angles in the same segment)
Thus, ∠ABC=∠ABD+∠CBY=(82+46)°=128°
Answer: ∠ABC=128°
