Question

Please help! Will give medal!

Answer 1

Did you finish this?

Answer 2

no :/

Answer 3

Is ADE and AOC similar?

Answer 4

yes

Answer 5

Then what do you think about the ratios AE/AC and AD/AO?

Answer 6

do would be 25

Answer 7

right?

Answer 8

No. Actually,\[\frac{ AE }{ AC }=\frac{ AD }{ AO }\rightarrow AO=\frac{ AC \times AD }{ AE }=\frac{ 40 \times 12 }{ 15 }=32\]Therefore, DO = AO - AD

Answer 9

so how would i respond to this

Answer 10

i need to call my teacher and give her the answer, what would i tell her when he asks me about do and of

Answer 11

do is 32

Answer 12

Nope. DO = AO - AD

We know that AO = 32 and AD =12, then DO = 32 - 12 = 20

Answer 13

oh okay :)

Answer 14

and OF?

Answer 15

Sorry, I am thinking. Thank you for you patience.

Answer 16

take your time :)

Answer 17

Are OD and EF parallel?

Answer 18

yupp

Answer 19

Then DE = OF

Answer 20

how would we find DE?

Answer 21

You might call DE x. Then\[\frac{ AE }{ AC }=\frac{ DE }{ OC }\rightarrow \frac{ 15 }{ 40 }=\frac{ x }{ x+30 }\]You can now solve for x. The final answer is x = DE = OF

Answer 22

If you get 18, then you are right.

Answer 23

DO = 20 and OF = 18

Answer 24

Yes

Answer 25

wow thank you so much :-)

Answer 26

You are very welcome
