Answer 1

Answer:

IF THIS IS A TRIANGLE AND WE HAVE ABC THENWHERE DO BDC AND BEC COME FORM??

Step-by-step explanatio

                           

Answer 2

Answer:

△ABC is an isosceles triangle.

∴∠B=∠C=50

o

∠BAC=180−50−50=80

o

∠BAC=∠BDC=80

o

(angles on circle by the same chord on the same side)

∠BEC is supplementary angle of ∠BAC

∴∠BEC=180−∠BAC

=180−80=100
