that's ok
AB corresponds to FG
So FG/AB = 6/8 = 0.75 is the number you multiply each side length in the larger pentagon to get the corresponding side length in the smaller pentagon
8?
8 times 0.75 = 6
oh wait, i read that wrong...one sec
oh for some reason, it still works out...lucky coincidence but yes, you multiply by 0.75
oh
to go backwards, you divide by 0.75
notice how FJ corresponds to AE
and FJ = 6 So AE = FJ/0.75 = 6/0.75 = 8 which means AE = 8
so then i had it right?
yes, sry i didn't see that til now
ok, cool and for #14 it would be 2.5?
no no no it would be 3
which side corresponds to IJ?
CD, so it would make it 3? correct?
this is why this problem is a bit confusing
the second pentagon should be rotated slightly clockwise so that FG matches up with AB
now tell me what ij corresponds to
8
did you do the rotation? this will make F the bottom most point
yea
so ij corresponds to ???
which side from ABCDE
de
good
now multiply that length by 0.75 to find ij
2.5
try it again 5 times 0.75 = ???
de = 5
3.75
good
fg would be 4?
fg corresponds to ???
ab?
good FG = 0.75 times AB
6
you nailed it
thanks, this will be the last one i promise

The two triangles are similar So AD/ED = BD/CD 35/16 = 25/x Now solve for x
9.6?
no
35/16 = 25/x 35x = 16*25
7 6/7
no it's not any of those answer choices
x is the length of CD
which isn't listed
16*25=400
good
35x = 16*25 35x = 400
dfsdfdddddddd
sorry cat walked on the kep board... and i dont get wat i do next
key*
that's ok, divide both sides by 35
45 divided by 35, and what else by 35?
11.4
ok now subtract this from 25
13.6
which is closest to which answer choice?
13 4/7
13.6 is closest to 13 6/7
your first response is correct
13.6 is closest to 13 4/7
which is the answer
13 4/7
yes
thank you,... i was just wondering, but are u like a teacher or something?
i'm a student learning to become one
your are amazing
why thank you, i appreciate the compliment
your are verry verry welcome, you helped me out so much that i officaly have a B in geometry ( summerschool) i had failed it the first time idurring the year, i dont know what i would have done with out you...
i'm glad i could help you out, you're very smart and it sounds like you're starting to get the hang of this stuff, which is great
