OpenStudy (dehydrated):

OpenStudy (3mar):

I am at your service!

OpenStudy (dehydrated):

@3mar is my answer right?

OpenStudy (3mar):

Just a check?

OpenStudy (dehydrated):

@3mar yes please

OpenStudy (dehydrated):

OH WAIT A SEC I HAVE THE WRONG ANSWER TYPED IN

OpenStudy (3mar):

I don't think so. Let's calculate it .. ok?

OpenStudy (dehydrated):

ok @3mar

OpenStudy (3mar):

what is the perimeter of the adult one?

OpenStudy (dehydrated):

167

OpenStudy (3mar):

\[\checkmark\] then can you calculate the reaming length of the adult trapezoid?

OpenStudy (dehydrated):

the adult one is 20

OpenStudy (dehydrated):

@3mar

OpenStudy (3mar):

Correct Are these shapes similar?

OpenStudy (dehydrated):

yes but one is small of course

OpenStudy (3mar):

Yes, that is logic, as I did not say "Congruent" what results in the similarity?

OpenStudy (dehydrated):

@3mar ew um I don't know after that

OpenStudy (3mar):

"The corresponding sides are proportional" Are you familiar with that?

OpenStudy (dehydrated):

@3mar somewhat

OpenStudy (3mar):

Great! Can you apply it to two pairs - with known lengths - of the these two similar shapes?

OpenStudy (dehydrated):

@3mar yes

OpenStudy (dehydrated):

would the sides be 35 then?

OpenStudy (3mar):

35 and 14 20 and G'A' right?

OpenStudy (dehydrated):

right

OpenStudy (3mar):

Do it and show your works, please sister!

OpenStudy (dehydrated):

ok one sec

OpenStudy (3mar):

Ok

OpenStudy (dehydrated):

@3mar I thought i had it but I obviously doing something wrong

OpenStudy (dehydrated):

am*

OpenStudy (3mar):

What you had? Show me and I will catch you!

OpenStudy (dehydrated):

so I know that em' is 21 inches shorter than em and by that then the sides of the prime would be 35 since 56-21 is 35 but then I realized tat wouldn't be possible because the top on the adult pinball machine is 20.

OpenStudy (dehydrated):

@3mar

OpenStudy (3mar):

"em' "???

OpenStudy (dehydrated):

@3mar E'M' AND EM

OpenStudy (dehydrated):

at this point I don't think I'll ever understand whats going on

OpenStudy (3mar):

Easy sister! GA = 20 EM = 35 E'M' = 14 ok?

OpenStudy (3mar):

\[\Large \frac{ GA }{ G'A' }=\frac{ EM }{ E'M' }\]now plug in their values!

OpenStudy (dehydrated):

I understand that part I just don't get how to find G'A'

OpenStudy (3mar):

2 min and I will be back

OpenStudy (dehydrated):

ok so EM/E'M' = 2.5

OpenStudy (3mar):

Sorry for late. Did you get it?

OpenStudy (3mar):

Thank you for the medal!
