1. yoooooooo

thats 2 0f them

2. yoooooooo

i did draw it and the question is find the value of each variable

3. yoooooooo

do u understand it now?

4. yoooooooo

@zordoloom

5. Youngster

so they are not parrallel, right?

6. yoooooooo

i dont think so @Youngster

7. Youngster

well with the triangle thing, use the property that an exterior angle is the sum of the opposite two interior angles, and solve using the system of equations

8. yoooooooo

thsnks but i still do not get it @Youngster

9. zordoloom

Are they separate questions?

10. ktnguyen1

ok I have the answer for 1 st one

11. yoooooooo

yes @zordoloom

12. ktnguyen1

x=36

13. yoooooooo

what is it and how do you do it @ktnguyen1

15. yoooooooo

thank you and can you or someone else help me with the other one

16. yoooooooo

can anyone help me @woksman @amistre64

17. tcarroll010

The first one is correct, x = 36. I didn't look at the second one yet.

18. yoooooooo

okay thanks and tell me when you get the second one

19. yoooooooo

@sn

20. tcarroll010

I can't work with the second one because I don't understand your diagram. Doesn't make sense to me the way it is written.

21. yoooooooo

@snaef999

22. yoooooooo

@snaef999

23. tcarroll010

Is that z - 13 and z + 10?

24. yoooooooo

yes @tcarroll010

25. snaef999

does that triangle have equal length sides? if so then all three interior angles are 60 deg

26. yoooooooo

i have no idea the only thing they gave me was what the picture has @snaef999

27. snaef999

I think you need to assume they are the same. I think that is the only way to do it. Otherwise you dont have enough info.

28. ktnguyen1

x=59 y=49 w=72 z=121

29. tcarroll010

z - 13 + w = 180 z + 10 + y = 180 x = 180 - (w + y) x + z = 180 Substitute equation #3 into equation #4. Use equations #1, #2, and #4 for 3 equations in 3 unknowns (z, y, and w). Solvable.

30. yoooooooo

i dont understand what your saying @tcarroll010

31. yoooooooo

how did you get that @ktnguyen1

32. ktnguyen1

|dw:1354572720749:dw| then you solve them

33. yoooooooo

ughhhh this is frustrating how do i solve that @tcarroll010 and @ktnguyen1

34. yoooooooo

@hieuvo on the second one

35. hieuvo

|dw:1354573487164:dw|

36. yoooooooo

it is hard thanks for helping @hieuvo

37. tcarroll010

z - 13 + w = 180 z + 10 + y = 180 x = 180 - (w + y) x + z = 180 Substitute equation #3 into equation #4. Use equations #1, #2, and #4 for 3 equations in 3 unknowns (z, y, and w). Solvable. z - 13 + w = 180 z + 10 + y = 180 180 - (w + y) + z = 180 So, we have: z + w = 193 z + y = 170 z - w - y = 0 Adding equation #2 to equation #3: z + w = 193 z + y = 170 2z - w = 170 Adding equation #1 to #3: z + w = 193 z + y = 170 3z = 363 So, z = 121. Easy to find the others now.

38. yoooooooo

thank you verrrrrrryyyyyyy much
