Question

abcd isa cyclic quadrilateral whise diaggonals intersect at a point E.if <DBC=70°,<BAC=30°,find <BCD​

Answer 1

Answer:

80°

Step-by-step explanation:

1)<DBC=70(GIVEN)

<BAC=30 (GIVEN)

2)<BDC=<BAC=30(ANGLES IN THE SAME ARC OR ANGLES MADE BY THE SAME CHORD ARE EQUAL)

3)<BCD=180-(70+30) --->(SUM OF ALL ANGLES OF A TRIANGLE IS 180)

=180-100

=80
