Er where is x in the diagram?

5. mckenzieandjesus

sorry i forgot that part

6. mckenzieandjesus

which of the following must be true? A.m<1>m2 B.m<1<m<2 C.m<1=m<2 D.m<1<m<2 |dw:1433878330495:dw|

@sdfgsdfgs

8. sdfgsdfgs

1st prob 1st - u may want to repost the second one separately.... triangle ABE and ACD are similar so their sides should be in the same ratio ok?

9. mckenzieandjesus

ok and ok

10. mckenzieandjesus

so how would I solve it?

11. sdfgsdfgs

What is the ratio of AB to AC?

12. mckenzieandjesus

60?

13. sdfgsdfgs

Not exactly - try this: what is length of AB and AC? Then divide AB/AC to find the ratio.

14. mckenzieandjesus

1?

15. sdfgsdfgs

What is length of AB?

16. mckenzieandjesus

30

17. sdfgsdfgs

How about AC? From point A to point C

18. mckenzieandjesus

60

19. sdfgsdfgs

So AB/AC=?

20. mckenzieandjesus

21. mckenzieandjesus

30/60= 1/2?

22. sdfgsdfgs

Nope, b is not the right ans sorry!

23. sdfgsdfgs

Correct - 1/2 is right now because the triangles are similar, BE/CD=AB/AC

24. mckenzieandjesus

so 1/2=1/2?

25. sdfgsdfgs

What are length of BE and CD?

26. mckenzieandjesus

60?

27. mckenzieandjesus

wait cd is 48

28. sdfgsdfgs

No, length between point B and E? Yes, CD is 48

29. mckenzieandjesus

im confused of how to figure that out..

30. sdfgsdfgs

Read your picture plz - the length is shown as what you are trying to solve here

31. mckenzieandjesus

3x

32. sdfgsdfgs

put in the values of BE and CD and ratio of AB/AC in: BE/CD = AB/AC What will you get?

33. mckenzieandjesus

9/16?

34. mckenzieandjesus

do i do 3/48 and 30/60?

35. sdfgsdfgs

YES, you just missed the x there, it should be 3x / 48 = 30 / 60 Solve for x and you get the ans.

36. mckenzieandjesus

30/60= 1/2 but how do i solve the other side?

37. sdfgsdfgs

3x / 48 =1/2 then multiply both sides by 48

38. mckenzieandjesus

39. mckenzieandjesus

be

40. sdfgsdfgs

No

41. sdfgsdfgs

What do u get by multiply both sides by 48?

42. mckenzieandjesus

i cant put x in my calculator when i do 3/48*48 i got 3

43. mckenzieandjesus

1/2*48 is 24

44. sdfgsdfgs

Put the calculator away, use it later.

45. sdfgsdfgs

and 3x/48 * 48 is equal to what?

46. sdfgsdfgs

$\frac{ 3x }{ 48 } * 48$ = ?

47. mckenzieandjesus

i cant do that without a calculator

48. sdfgsdfgs

A calculator cannot handle the "3x" part for u - sorry!

49. mckenzieandjesus

50. sdfgsdfgs

Good! so we now have: 3x=24 solve for x plz

51. mckenzieandjesus

x=8

52. sdfgsdfgs

Correct!

53. mckenzieandjesus

thank you lol

54. sdfgsdfgs

Welcome. Plz post the second prob separately. I need to go n cant help u w that one. Good luck!
