Question

In the given figure, ∠BAD = 65°, ∠ABD = 70° and ∠BDC = 45°. Find: ∠BCD 
Hence, show that AC is a diameter

Solution

In cyclic quadrilateral ABCD,

∠BCD = 180° - ∠BAD = 180° - 65° = 115°

(pair of opposite angles in a cyclic quadrilateral are supplementary)

  Is there an error in this question or solution?
