## anonymous one year ago What is the value of w in terms of x and y?

1. anonymous

aka "solve for $$w$$ " right?

|dw:1435716265419:dw|

3. anonymous

I'm not sure...

4. anonymous

if that is a straight line on the right, then $$2x+w=180$$

5. anonymous

yea

6. anonymous

so you can solve for $$w$$ with no $$y$$ in it , just $w=180-2x$

7. anonymous

The answer to this is w=2x+2y-180

8. anonymous

i have no clue how that's the answer

9. anonymous

me neither

10. anonymous

crap

11. anonymous

i am sure we can figure it out if we stare long enough

12. anonymous

yea that's the only strategy i have thus far

13. anonymous

we got a bunch of stuff we know for example $x+y+k=180$

14. anonymous

yea

15. anonymous

$w+2k=180$

16. anonymous

yea i got that

17. anonymous

we can solve $w+2k=180$ for $$k$$ and get $w=180-2k$then plug that in to the first one

18. anonymous

yea

19. anonymous

oops that is wrong, i meant "solve for $$k$$"

20. anonymous

$k=\frac{180-w}{2}$

21. anonymous

hmmm okay

22. anonymous

plug that in h ere $x+y+k=180$

23. Kash_TheSmartGuy

This is confusing!

24. anonymous

$x+y+\frac{180-w}{2}=180$ then solve that for $$w$$

25. anonymous

wow u kno what i'm just going to skip this because this is way too hard

26. anonymous

it is not that hard takes three steps at the most

27. anonymous

multiply by 2 get $2x+2y+180-w=360$

28. anonymous

add $$w$$ subtract $$360$$ get $2x+2y-180=w$

29. anonymous

wow you got it..... okay well lemme sit here and stare for a bit to process this..

30. anonymous

so another method would be K=(180-x-y) w+k+k=180 w=180-2k w=180-2(180-x-y) w=180-360+2x+2y w=2x+2y-180
