O is the center of the circle. Find the value of x, y, and z.

2. Directrix

Is 80 an angle measure, segment length, or what?

3. Directrix

@Mrfootballman97

4. Mrfootballman97

its a degree: |dw:1361764300764:dw|

5. Directrix

To which angle does the 80 go?

6. Mrfootballman97

@Directrix

7. Mrfootballman97

i attached it to its angle

8. Mrfootballman97

Well the first diagram i put up was what was in my book. ill put up a pic of the original

9. Mrfootballman97

ill just draw it again. |dw:1361765174710:dw|

10. Mrfootballman97

Is that more clear?

11. Directrix

Yes. Let us think a minute.

12. Directrix

I don't see how that 80 degree angle could actually be 80 degrees if it is located and correctly marked.

13. Directrix

An angle formed by a chord and a tangent on a circle has measure 1/2 its intercepted arc. So that arc would be 160.

14. Directrix

Assuming the the exterior segment is a tangent. It was not given to be.

15. Directrix

I see three congruent chords in the same circle. So they have congruent arcs.

16. Directrix

160*3 exceeds the number of possible degrees in a circle. So, I don't know what to write. Are you sure you posted all the given information?

17. Mrfootballman97

Yup. Ill give you a medal for the help though. Thanks!
