2. Mrfootballman97

but it has all the info. Do you need me to rewrite it?

3. Mrfootballman97

oh i think its 2

4. Mertsj

Is the center of the circle indicated?

5. Mrfootballman97

|dw:1362963306954:dw| The black dot

6. Mrfootballman97

I think if: 1. Chords are = distance from center they are congruent. and 2. Congruent chords are = distance from center.

7. Mertsj

Ok. That's what I figured. We need to use the Pythagorean Theorem to find the radius of the circle. Also we need to remember that a radius that is perpendicular to the chord bisects the chord.

9. Mertsj

What you posted is true, however, the chords in your picture are not the same length are they?

10. Mrfootballman97

no. In the original pic they are not either.

11. Mertsj

One of them is 4 and the other one is 8, is that right?

12. Mrfootballman97

yeah

13. Mertsj

14. Mrfootballman97

ya

15. Mertsj

16. Mrfootballman97

1 sec

17. Mrfootballman97

not really

18. Mrfootballman97

is it 4?

19. Mertsj

20. Mrfootballman97

oh wait

21. Mertsj

I'm just not sure about the picture.

24. Mertsj

Do you think that BC is 4 or AC is 4?

25. Mrfootballman97

i think bc

26. Mertsj

Do you think that DE is 8 or DF is 8?

27. Mrfootballman97

DE

28. Mertsj

Well then, you are right congruent chords are the same distance from the center and x=2

29. Mrfootballman97

ok thanks
