Question

This is a GEometry problem attachments included

Answer 1

first one is c

Answer 2

i got that :3 and the second one?

Answer 3

what did you get?
i hope its what i got...

Answer 4

the same :3

Answer 5

yeah, but for the 2nd one, what did you get?

Answer 6

that is where im confused :0

Answer 7

you need to work out E to F then divide that by DE

Answer 8

ok 1 min

Answer 9

and you have to remember that the picture they have is not to scale

Answer 10

is it 7.6?

Answer 11

i agrizzle

Answer 12

so its correct? :3

Answer 13

it is not 7.6 try again. find first the EF. which is, 30 - 18 = 12

the ratio is:

GH : 8 = 18 : 12

what you do is, divide 12 by 8, multiply it to GH. Then equate it to 18.

like this,

(12/8)GH = 18

my answer is not 7.6

Answer 14

yeah, im pretty sure

Answer 15

its 12 isn't it. thats what i started with but then i looked at the diagram again, and thought that cant be right because those other lines arent parallel

Answer 16

oh so its 12

Answer 17

when i say "its 12 isn't it." im talking about theawesomes answer not what the actual answer is

Answer 18

ooooooooo my bad

Answer 19

it might be, but see the proportion.

GH should be larger than HI, since DE is larger than EF.

Answer 20

so, 7.6 can't be the answer since it is smaller than 8. you're defying the proportion given in question 6.

plus, solve it mathematically, it gives you 12. so, I say it is 12.

Answer 21

no, it shouldn't because of that exact reason... it'd only be the same ratio if they were parallel.

but because they're coming together then it has to be smaller

Answer 22

okay. i understand that. but can you show me how you got 7.6?

Answer 23

no

i dont want to :(

Answer 24

I'm getting 12 as well. 8 (18/12)=12.

Answer 25

yeah, i think that diagram just put me off

i honestly started with 12 as my answer

Answer 26

Okay. So 12 it is.

Answer 27

Thank you all

Answer 28

sigh, yes.
