(see attachment)

Answer 1

help c:

Answer 2

Okie,just wait for a few minutes. I PMd someone who might be of assistance.

Answer 3

\(\bf \cfrac{2}{4}=\cfrac{10}{x}\qquad then\\ \quad \\

\cfrac{2}{4}=\cfrac{y}{x}
\)

Answer 4

i was typing a long explanation but jdoe got to iht .-.

Answer 5

You split up the triangles .. OHHHH c:

Answer 6

solving for x & y then finding the missing length?

Answer 7

there is no y though ._.

Answer 8

hehe,....right.. "y" is just the side you're after, since I used up "x' =)

once you find "x", using the firsts ratio set, you'd find the corresponding side for the missing side on the 2nd triangle, I just happen to name it "y" =)

Answer 9

\[\frac{ 2 }{ 4 } = \frac{ 10 }{ x }\]
cross multiplication I think, my memory of geometry is rusty..

Answer 10

\(\bf \cfrac{2}{4}=\cfrac{10}{\square }\qquad then\\ \quad \\

\cfrac{2}{4}=\cfrac{x}{\square }\) =)

Answer 11

2x = 40
find x
then put put the result of that into
\[\frac{ 2 }{ 4 } = \frac{ y }{ x }\]

Answer 12

and cross multiply and solve for y.

Answer 13

That's one of my example problems.
