Question

The OR part of Q.32

Answer 1

Step-by-step explanation:

In triangle ABC;

given:AB=AC

<ABC=50°

<ABC=<ACD. because because in an isosceles triangle angles opposite to the equal sides are also equal.

50°=<ACD

<ABC+<BAC+<ACD=180°

50+50+<BAC=180

100°+<BAC=180

<BAC=180-100

<BAC=80

<BAC=BOC. angles in the same segment are equal

80=<BOC
