Answer 1

Step-by-step explanation:

Given,

△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
