Hey mate !!❤✌
here's ur answer ⤵⤵⤵⤵⤵
______________________________
Given: ABCD is a kite and ∠BCD=40°We know that in a kite smaller diagonal bisects the angle.⇒∠BCA=∠ACD=12∠BCD=40°2=20°and also diagonals of kite bisect each other at 90°so, ∠AOD=∠AOB=∠BOC=∠COD=90°In △DOC, by angle sum property of △⇒∠DOC+∠OCD+∠CDO=180°⇒90°+20°+∠CDO=180°⇒∠CDO=180°−110°⇒∠CDO=70°=∠BDCNow AB=BC⇒∠BCA=∠BAC=20° [angles oppoite equal sides are equal.]Now in △ABC , by angle sum property of △⇒∠ABC+∠BCA+∠CAB=180°⇒∠ABC+20°+20°=180°⇒∠ABC=180°−40°⇒∠ABC=140°
