ABCD is cyclic quadrilateral. The tangents to a circle at A and C meet at P. If ∠ APC = 50∘, then the value of ∠ ADC is:
If ABCD is a cyclic quadrilateral with AB as the diameter of the circle and ∠ACD=50∘, then ∠BAD = ___.
ABCD is a cyclic quadrilateral whose diagonals intersect at a point E. If ∠DBC=70∘,∠ACD is 50∘, find ∠ADC.
ABCD is cyclic quadrilateral such that AB is a diameter of the circle circumscribing it and ∠ADC=140∘, then ∠BAC is equal to
(A) 80∘ (B) 50∘ (C) 40∘ (D) 30∘
