In circle w arc xz =60 degress , angle VYZ= 40 and line YZ is the diameter. Find the following <XWY, arc YWZ, arc xy, arc vy, <wxy,<wxy,<yvx, arc vZ. <VZY

5. baby456

yes

Now you should be able to get arc XY.

8. baby456

how?

9. anonymous

The whole circle is 360°. arc XY is the only part still missing.

10. baby456

so its 80

11. anonymous

|dw:1433024793372:dw|

12. anonymous

not 80. 360-60-80-100

13. baby456

wait how did you get 80 and 100

14. baby456

oh i see how.

|dw:1433024967910:dw|

16. baby456

i still lost.

17. baby456

i am still lost

18. anonymous

Do you understand how I got 80 for arc VZ?

19. baby456

yes i caculator all of that arc xy is 40.

20. anonymous

it's not 40. How did you do it?

21. baby456

360-100-80-60

22. anonymous

that's 120°

23. baby456

ok i added something wrong sorry

26. anonymous

Is that everything you were looking for?

27. baby456

<wxy

28. anonymous

Something isn't right with this. Does XV pass through W?

29. anonymous

in the original picture?

30. baby456

@peachpi come back please

31. baby456

can someone help anybody please

32. anonymous

I roam

33. anonymous

Can you tell from the picture if XV also a diameter of the circle?

34. baby456

<Yvz

35. baby456

and angle vzy

36. anonymous

how do u give medals?

37. anonymous

@skyfire41505 hit the best response button.

38. anonymous

@baby456 something in this picture doesn't work. We worked this so far based on the assumption that segment XV is not a diameter. If we stick with that we end up with vertical angles that aren't equal. If I change it to assume the XV is a diameter, then arc VZ is 120°, which is impossible since its angle is 40°

@pooja195 am I wrong here?

40. baby456

but that what my teacher gave me.

41. pooja195

i dont know this :(

42. baby456

i think i'm done with geometry i have to go sigh|dw:1433027011268:dw|

working with the numbers we have, <yvx is 60°, but consider the note above.
