In the given figure, O is the centre of ...

In the given figure, O is the centre of a circle and `/_ OAB = 50^(@)`. Then . `/_ BOD = ? `

A

`130^(@)`

B

`50^(@)`

C

`100^(@)`

D

`80^(@)`

Text Solution

Verified by Experts

The correct Answer is:
C
`OA= OB implies /_ OBA = /_ OAB = 50^(@)`
ln `Delta OAB, /_ OAB + /_ OBA+ /_AOB= 180^(@) implies 50^(@) + 50^(@) + /_ AOB = 180^(@)`
`:. /_ AOB = 80^(@)`
`:. /_ BOD = 180^(@) - 80^(@) = 100^(@)`
