Question

Part-B
If O is the centre of the circle, find the x in below figure:
​

Answer 1

Step-by-step explanation:

angle BDC=35°( angle in the same segment form by chord BC)

35+65+x=180

x=180-100=80°

Answer 2

Answer:

it will be 80° as angle BAC will be equal to angle BCD(angle in a segment), then BDC=35, DBC=65 then obviously angle DCB will be 80
