Question

in the given figure o is the centre of the circle and ABC is equilateral find angle BDC and angle bec​

Answer 1

Step-by-step explanation:

ABC is an equilateral triangle.

∠BAE=60

ABEC is a cyclic quadrilateral.

We know,

∠BAC+∠BEC=180

=>∠BEC=180−60

=120

We know that the angles subtended by an arc on the circumference on the same side are equal.

Therefore,

∠ABC=∠BDC

=>∠BDC=60
