princeevee:
i need someone to check my answers
princeevee:
@Vocaloid back yet?
Vocaloid:
hm, not quite. the altitudes have the same scale factor as the sides do so TV/ZX = SU/WY plug in everything and solve for WY
princeevee:
so it was A? that was actually my first choice but i thought it wasnt it
Vocaloid:
good, A
Vocaloid:
hm. I got something a little different. LM/RQ = MO/RT solve for MO
Vocaloid:
still there? plugging in the sides gives us 12.6/3 = MO/4.5 MO = ?
princeevee:
B?
Vocaloid:
check your calculations again 12.6/3 = MO/4.5 multiplying both sides by 4.5, gives us: (12.6/3)*4.5 = MO = ?
princeevee:
18.9
Vocaloid:
good
Vocaloid:
gonna go out to run a quickish errand be back soon
princeevee:
okay
Vocaloid:
check your proportion again side of big triangle/side of small triangle = altitude of big triangle/altitude of small triangle
princeevee:
i did a bit more, and i got somewhere near D
Vocaloid:
good
Vocaloid:
good
Vocaloid:
remember what we said earlier side of big triangle/side of small triangle = altitude of big triangle/altitude of small triangle D follows this set up exactly so D is not the solution
jhonyy9:
check it again bc. the last one is true
Vocaloid:
it asks for the proportion that is not true so you want the ratio that is ~not~ comparing corresponding sides or altitudes in the right order
jhonyy9:
you need getting what choice not is proportionality of corresponding sides
jhonyy9:
@princeevee do you understand it ?
princeevee:
slightly
jhonyy9:
ok begin it step by step 1. to side DB correspond side PN - yes ?
princeevee:
yeah..
jhonyy9:
so to side CD correspond side PM ?
jhonyy9:
@princeevee how you think it please ?
princeevee:
what?
jhonyy9:
to side AD correspond side MP in this case to side CD what side will correspond ?
jhonyy9:
|dw:1529264284448:dw|
Vocaloid:
they're just asking you what side corresponds with CD look at the position of CD on the big triangle and find the matching side on the small triangle.
princeevee:
PO?
jhonyy9:
so than to CD correspond PO in this case the first choice may be true ?
Vocaloid:
good now look at the first answer choice again is the proportion comparing corresponding parts?
jhonyy9:
courage @princeevee this is easy
Vocaloid:
|dw:1529264797607:dw|
Vocaloid:
let's highlight what is being compared with the two ratios DB/PN|dw:1529264814396:dw|
princeevee:
alright...
Vocaloid:
now CD/PM |dw:1529264839580:dw|
Vocaloid:
are the ratios equal?
princeevee:
yeah?
Vocaloid:
are PM and CD corresponding sides?
princeevee:
no?
Vocaloid:
then the ratios are not equal
Vocaloid:
that being said what is the final solution?
princeevee:
A?
Vocaloid:
good
Vocaloid:
good
Vocaloid:
hm not quite CD/PO = DB/PN plug the sides in and solve for DB
princeevee:
wait, C?
princeevee:
hang on, i'm not getting this much..
Vocaloid:
C is correct CD = x PO = y PN = z plugging them in gives us x/y = DB/z so xz/y
Vocaloid:
not quite remember we want the ratio that is comparing sides that are ~not~ corresponding
Vocaloid:
try to go through each answer choice, highlight the lines that are being compared, then see if two sets of corresponding sides are being compared or not
princeevee:
C?
Vocaloid:
|dw:1529266051474:dw|
Vocaloid:
|dw:1529266056090:dw|
Vocaloid:
C is comparing the corresponding line segments so C cannot be the solution
Vocaloid:
we would want the ratio where ~non~ corresponding parts are being compared
princeevee:
only one i'm thinking of left is A
Vocaloid:
hint: are BC and KL corresponding sides?
princeevee:
no.
Vocaloid:
then do you think altitude of big triangle/altitude of small triangle = BC/KL?
princeevee:
ah, alright then!
Vocaloid:
good
Vocaloid:
hm, not quite, those aren't corresponding sides so the ratio won't be equal you can set up a ratio with LM/PQ = LJ/PN try to plug all the # values in and see which ratio you get
Vocaloid:
looking at the diagram... LM = 0.9 PQ = 1.4 LJ = 0.7 plugging these into LM/PQ = LJ/PN gives us...?
princeevee:
0.9/1.4 = 0.64
Vocaloid:
notice how the answer choices just have the ratios set up but not solved you don't have to solve the ratio, just plug the side values into LM/PQ = LJ/PN and see which answer choice matches.
princeevee:
A?
Vocaloid:
good.
