sorry i forgot that part
mckenzieandjesus
  • mckenzieandjesus
which of the following must be true? A.m<1>m2 B.m<1

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?
mckenzieandjesus
  • mckenzieandjesus
ok and ok
mckenzieandjesus
  • mckenzieandjesus
so how would I solve it?
sdfgsdfgs
  • sdfgsdfgs
What is the ratio of AB to AC?
mckenzieandjesus
  • mckenzieandjesus
60?
sdfgsdfgs
  • sdfgsdfgs
Not exactly - try this: what is length of AB and AC? Then divide AB/AC to find the ratio.
mckenzieandjesus
  • mckenzieandjesus
1?
sdfgsdfgs
  • sdfgsdfgs
What is length of AB?
mckenzieandjesus
  • mckenzieandjesus
30
sdfgsdfgs
  • sdfgsdfgs
How about AC? From point A to point C
mckenzieandjesus
  • mckenzieandjesus
60
sdfgsdfgs
  • sdfgsdfgs
So AB/AC=?
mckenzieandjesus
  • mckenzieandjesus
would the answer be b?
mckenzieandjesus
  • mckenzieandjesus
30/60= 1/2?
sdfgsdfgs
  • sdfgsdfgs
Nope, b is not the right ans sorry!
sdfgsdfgs
  • sdfgsdfgs
Correct - 1/2 is right now because the triangles are similar, BE/CD=AB/AC
mckenzieandjesus
  • mckenzieandjesus
so 1/2=1/2?
sdfgsdfgs
  • sdfgsdfgs
What are length of BE and CD?
mckenzieandjesus
  • mckenzieandjesus
60?
mckenzieandjesus
  • mckenzieandjesus
wait cd is 48
sdfgsdfgs
  • sdfgsdfgs
No, length between point B and E? Yes, CD is 48
mckenzieandjesus
  • mckenzieandjesus
im confused of how to figure that out..
sdfgsdfgs
  • sdfgsdfgs
Read your picture plz - the length is shown as what you are trying to solve here
mckenzieandjesus
  • mckenzieandjesus
3x
sdfgsdfgs
  • sdfgsdfgs
put in the values of BE and CD and ratio of AB/AC in: BE/CD = AB/AC What will you get?
mckenzieandjesus
  • mckenzieandjesus
9/16?
mckenzieandjesus
  • mckenzieandjesus
do i do 3/48 and 30/60?
sdfgsdfgs
  • sdfgsdfgs
YES, you just missed the x there, it should be 3x / 48 = 30 / 60 Solve for x and you get the ans.
mckenzieandjesus
  • mckenzieandjesus
30/60= 1/2 but how do i solve the other side?
sdfgsdfgs
  • sdfgsdfgs
3x / 48 =1/2 then multiply both sides by 48
mckenzieandjesus
  • mckenzieandjesus
would the answer by 3?
mckenzieandjesus
  • mckenzieandjesus
be
sdfgsdfgs
  • sdfgsdfgs
No
sdfgsdfgs
  • sdfgsdfgs
What do u get by multiply both sides by 48?
mckenzieandjesus
  • mckenzieandjesus
i cant put x in my calculator when i do 3/48*48 i got 3
mckenzieandjesus
  • mckenzieandjesus
1/2*48 is 24
sdfgsdfgs
  • sdfgsdfgs
Put the calculator away, use it later.
sdfgsdfgs
  • sdfgsdfgs
and 3x/48 * 48 is equal to what?
sdfgsdfgs
  • sdfgsdfgs
\[\frac{ 3x }{ 48 } * 48\] = ?
mckenzieandjesus
  • mckenzieandjesus
i cant do that without a calculator
sdfgsdfgs
  • sdfgsdfgs
A calculator cannot handle the "3x" part for u - sorry!
mckenzieandjesus
  • mckenzieandjesus
the answer is still 3x
sdfgsdfgs
  • sdfgsdfgs
Good! so we now have: 3x=24 solve for x plz
mckenzieandjesus
  • mckenzieandjesus
x=8
sdfgsdfgs
  • sdfgsdfgs
Correct!
mckenzieandjesus
  • mckenzieandjesus
thank you lol
sdfgsdfgs
  • sdfgsdfgs
Welcome. Plz post the second prob separately. I need to go n cant help u w that one. Good luck!
