Question

help me please....urgent got ma math exam in a couple of hours​

Answer 1

Answer:

∠BDA

= ∠BCA               [ because they're both subtended by the chord BA ]

= ∠BCE               [ because CB bisects angle ∠ACE ]

= 180° - ∠BCD     [ because they're in a straight line ]

= ∠BAD              [ because opposite angles of a cyclic quadrilateral are supplementary]

Therefore ΔBAD is isosceles.

Therefore BD = BA.
