Answer 1

Step-by-step explanation:

we use the property i.e, angles on the same arc are equal.

from the above figure,

angle ABD = x and angle ACD = x , as both angles are in the same arc ABD .

&

angle CAB = y angle CDB = y , as both agles are in the same arc CAB .

so,

angle ABD = angle ACD = x

&

angle CAB = angle CDB = y
