3. Mertsj

|dw:1362958715978:dw|

4. Mertsj

Is O the center of the circle?

5. Best_Mathematician

do ya wanna find length of ABC? if yes then u need radius if no then i will figure it out

6. Mrfootballman97

Yes O is the middle. and i think i need the length of the chord ABC. At least that what i think it means

7. Mertsj

If what you have written at the bottom of the drawing is correct, you need to find the length of arc ABC. Is it correct?

8. Mertsj

It is necessary to the solution of a problem to know what we are trying to find.

9. Mrfootballman97

Yeah i got the chord and arc mixed up.

10. Mertsj

|dw:1362959283763:dw|

11. Mrfootballman97

Yes it is correct

12. Mertsj

Do you know what central angles are?

13. Mrfootballman97

yeah

14. Mertsj

Do you know that central angles are equal to their arcs?

15. Mrfootballman97

No. I think i forgot that.

16. Mertsj

Can you solve the problem now?

17. Mrfootballman97

Uhmm can you tell me the steps?

18. Mertsj

What is the measure of arc AOB?

19. Mrfootballman97

67

20. Mertsj

What is the measure of arc COB?

21. Mrfootballman97

55. Do i add 55 and 67?

22. Mertsj

yes

23. Mrfootballman97

ahhh! thanks man!

24. Mertsj
