Question

In the adjoining figure O is the centre of the circle find the measure of angle x​

Answer 1

Answer:

40 degrees is the answer

Answer 2

Answer:

x= 40° is the answer

^DAO=50° as OA and OD are radius of circle.so both angle same

^AOD=180-100=80°

^AOD +^ DOC= 180°

80°+ ^DOC= 180

^ DOC= 100°

in ∆ DOC , OC = OD.

so, ^ OCD= ^ODC

SO, ^ OCD = 40°= X
