Question

AB=34,BC=12, and CD=8. What is the value of x?

Answer 1

Not sure how to do this one

Answer 2

First, are you studying ratios? Any additional information?

Well, we can first say that AC = 46.

We know BC = 12 and CD = 8, so there is a common ratio of 4:1

Answer 3

Use the concept:

CA X CB=CD X CE

Answer 4

@AravindG 42*8 = 8 * CE? (CE? is that a typo?)

@Compassionate the only additional info is that the diagram is not drawn to scale.

Answer 5

wait…but it is a perfect circle isn't it? so i would think that you'd be able to use a proportion, but idk >_<

Answer 6

@AravindG sometimes has his 'special' moments.

Answer 7

Lol there was no name for the other endpoint So I took it as E. It is basically the chord theorem:

The chord theorem states that if two chords, CD and EF, intersect at G, then CG * DG = EG * FG. (Chord Theorem)

Answer 8

I dont think im following TBH. You took X as E?

Answer 9

For some strange evil magic my draw button is not working :|

Answer 10

black magic has gotten into the system of OS, there are a couple of malfunctions going on

Answer 11

@AravindG Dinkleberg!

Answer 12

\ban black magic

Answer 13

soooo back to the question >_>

Answer 14

\ban:user;"black<br>magic"

Answer 15

is x 43 as well?

Answer 16

I would lmao if that's actually a user ._.

Answer 17

X is on a ratio of 4:1, @Ashleyisakitty

Answer 18

Apparently, Aravand and I are solving it differently.

We can't both be right, but he can be wrong.

Answer 19

Once you get CE, x=CE-CD

That is the idea.

Answer 20

@Compassionate *Aravind

Answer 21

but i dont understand how to get to CE D: 34*4?

Answer 22

or.. 42? again? im confused.

Answer 23

@ArrowvindC , sure. e.e

Answer 24

very critical.. must hurry please

Answer 25

;-;

Answer 26

You have all the data. Use it!

Answer 27

Okay, lets get back to your question, now that @ArevendH has stopped distracting me.


Like I said, that ratio is 4:1

(AB=34,BC=12, and CD=8. What is the value of x?)

So, if AB = 34 and BC = 12, and CD = 8, then we can say that AC = 46.

Which means, 46 to a ratio of 4:1 = ?

Answer 28

@arovondF, where are you getting that from? We should use ratios.

Answer 29

See theorem 2

Answer 30

Uh is it

4+1=6
46/5=9.2
9.2*4=36.8
so 38.8:9.2??

Answer 31

**is still lost and confused

Answer 32

4+1=6

I dont want to live in this world anymore :|

Answer 33

simple typo.

Answer 34

Saved. http://prntscr.com/2l6v03

Answer 35

You are still going with Compassionate's method? He took the ratio wrong. Di you even try the method I suggested? :|

Answer 36

You just need to plug in those numbers and multiply :/

Answer 37

^

Answer 38

SO CE IS 43?

Answer 39

Aravind, okay, this isn't going well. We have completely separate methods.

Answer 40

Try this

46*12=(8+x)*8

Solve for x!

Answer 41

61...

Answer 42

Finally :)

Answer 43

Easy!

46*12=(8+x)*8
46 * 12 = 6
72 + 8x

So we have 6 = 72 + 8x
-66 = 8x
x = -8.25

@AravindG

Answer 44

thank you for your patience... running on 5 hrs of sleep trying to finish this semester

Answer 45

o.o Meanwhile in Saturn.....

Answer 46

@Ashleyisakitty yw :)

Answer 47

46 * 12 doesn't equal 6 :/?
