alwaz remember angle at the centre is equal to twice the angle at the circumfrence

3. manishsatywali

it's the property of circle

So it's 114?

5. manishsatywali

BOC = 2times angle BAC NW CHECK UR RESULT

6. manishsatywali

IF U NEED PROOF I CN GIVE U THAT ALSO

I'm very confused. :(

PLS TRY TO DO WAT I M SAYING INSTEAD OF REACHING TO ANY CONCLUSION

10. pratyush5

dont be confused . |dw:1359395777798:dw| see if the angle subtended by the arc at the centre is x then the angle at the circumference will be x/2

11. pratyush5

now here the arc is BD . just co relate and solve

I see now. Thanks. :)

13. pratyush5

ur welcome. what answer did you get ?

Would you mind going over my last one?

15. pratyush5

No, this one. I got 28.5 for the first one. :)

17. pratyush5

use the same logic for the arc qn and yu get angle 0 = ?

18. pratyush5

its easy just use the same logic

Got it. Thanks. :)

20. pratyush5

so wat answer do yu get ?

44.

22. pratyush5
