In figure, if `angleAOB=125^(@), then angleCOD` is equal to

A

`62.5^(@)`

B

`45^(@)`

C

`35^(@)`

D

`55^(@)`

Text Solution

Verified by Experts

The correct Answer is:
D
We know that, the opposite sides of a quadrilateral cricumscribing a circle subtend supplementary angles at the centre of the circle.
i.e., `angleAOB+angleCOD=180^(@)`
`rArrangleCOD=180^(@)-angleAOB`
`=180^(@)-125^(@)=55^(@)`
