Plzz ans fast!!! Q). In given fig., AB is diameter of circle C D ∥ A B and ∠ B A D = 60 ° . Find ∠ A C D . Share with your friends Share 0 Abhishek Jha answered this Dear Student, Here is the solution of your asked query: Since, AB is the diameter of circle so we have;∠ACB = 90° {Angles in a semicircle }∠BAD=60°We know that sum of opposite angles of cyclic quadrilateral is 180°, so we have;∠BAD+∠BCD=180°⇒60°+∠ACB+∠ACD=180°⇒∠ACB+∠ACD=120° {since ∠ACB = 90°}⇒90°+∠ACD=120° ⇒∠ACD=30° Regards 0 View Full Answer
