## youngnephew34 one year ago What is the value of x in Rhombus QRST A)16 B)12 C)8 D)4 Can somebody help me check my work PLZZZZZZZZZZZZ medal and fan and also I'll draw it out for you

1. youngnephew34

|dw:1440155955384:dw|

2. Astrophysics

|dw:1440156297957:dw| is this it? What is the 8 and 12 here, angles?

3. youngnephew34

yes

4. youngnephew34

you suppose to find the problem to that rhombus because it's a parallelogram

5. Astrophysics

This isn't a very clear image, so is it like this then |dw:1440156635413:dw|

6. youngnephew34

no

7. youngnephew34

|dw:1440156729213:dw|

8. youngnephew34

like that

9. Astrophysics

Ok but is the rest correct? Like the right angles

10. youngnephew34

yes

11. youngnephew34

|dw:1440156895178:dw|

12. youngnephew34

yes but the 8 goes on top and the 2x goes on the bottom

13. Astrophysics

I don't know what you mean

14. youngnephew34

and the 3x goes on your right side and the w 12 goes on the top right corner

15. youngnephew34

ok Imma show you

16. youngnephew34

yes correct

17. youngnephew34

you know doing 90 degrees angle this is parallelogram of property

18. Astrophysics

Well actually there is something wrong because then these aren't triangles

19. youngnephew34

so you know how they do distributive of property but this is like that but only different

20. Astrophysics

Can you just take a screen shot of your problem

21. Astrophysics

Rhombus is a kind of parallelogram, I just don't really understand your image

22. youngnephew34

23. youngnephew34

there you go

24. youngnephew34

did you see the image

25. Astrophysics

Yeah ok I see, I haven't done this since I was in junior high so lets see...

26. youngnephew34

TBH tho I thought it was 4

27. youngnephew34

28. phi

the diagonals of a rhombus bisect each other you can write 8= 2x

29. phi

also, 3x=12

30. Astrophysics

Or yeah haha just go with phi, I'm stupid when it comes to geometry xD

31. youngnephew34

ok

32. youngnephew34

so how do you do that cause I did it different

33. phi

if you use 2x= 8 divide both sides by 2, like this $\frac{2x}{2} = \frac{8}{2}$ or $\frac{2}{2}x = \frac{8}{2}$

34. phi

on the left side 2/2 is 1 and 1 times x is x what do you get on the right side?

35. youngnephew34

ok now I see but it's still the same answer I got 4 right

36. Astrophysics

Yeah I had got 4 as well haha

37. phi

yes, x=4 but you should be learning how to get the answer... it is not the answer that counts, it is learning how to get it. if you use 3x=12 divide both sides by 3 $\frac{3x}{3} = \frac{12}{3}$ what do you get for x?

38. youngnephew34

yea I did mines as 3x+12=2x+8

39. phi

you can't say that. the diagonals are not the same size

40. phi

if you get x=4 doing that, you "lucked out"

41. youngnephew34

I consul out the x and the 3x-2 =1x 1x+12=8 subtract both sides gives mi 1x=4 x=4

42. Astrophysics

|dw:1440158336109:dw| this is what I had originally as they bisect 3x=12, 2x = 8 @youngnephew34 bisect literally means to divide in two equal sides.

43. phi

1x + 12= 8 1x + 12-12 = 8-12 x= -4 so you don't get x=4

44. youngnephew34

nvm

45. youngnephew34

I got 2 more I want you guys to check

46. phi

we know x=4, and so we can figure out one of the diagonals is 16 and the other diagonal is 24 18 does not equal 24 but that is what you are saying if you write 2x+8= 3x+12 <-- not true.

47. youngnephew34

ok
