Hello Can you help me please? Long time no see! @jigglypuff314

OpenStudy (anonymous):

So False? :)

OpenStudy (anonymous):

I mean true Whoops

jigglypuff314 (jigglypuff314):

yeah :) true is correct

OpenStudy (anonymous):

I have a few more if you don't mind ?

jigglypuff314 (jigglypuff314):

of course :)

OpenStudy (anonymous):

jigglypuff314 (jigglypuff314):

huh? what's the question? :/

OpenStudy (anonymous):

True or False again :/

jigglypuff314 (jigglypuff314):

from what I see, there are no angles involved in the prove anywhere

OpenStudy (anonymous):

False? :)

jigglypuff314 (jigglypuff314):

yep :)

OpenStudy (anonymous):

jigglypuff314 (jigglypuff314):

you are given that the two triangles are similar and the inferred ratio of a pair of side as in 6 : 4 correspond so going from the left triangle to the right triangle, 6/4 = 1.5 so left triangle times 1.5 = right triangle so then 4.5 times 1.5 = n and 1.5m = 5 --> m = 5/1.5

OpenStudy (anonymous):

n=6.75?

jigglypuff314 (jigglypuff314):

yup :)

OpenStudy (anonymous):

That's not one of the choices ;o

OpenStudy (anonymous):

Unless it's D...? That's the closest... Since M= 3.33

jigglypuff314 (jigglypuff314):

oh well XD my brain isn't working so I'm just gonna use logic now :P left triangle has side 6 that corresponds to right triangle's side 4 6 > 4 so left triangle > right triangle so 4.5 > n and m > 5

OpenStudy (anonymous):

That's Definitely not right... :O

OpenStudy (anonymous):

Anyways this one should be false?

jigglypuff314 (jigglypuff314):

yeah false :)

OpenStudy (anonymous):

yey

jigglypuff314 (jigglypuff314):

mmm 8 d + 8 -- = ------ would be the proportion... 5 20 then x = d+8

OpenStudy (anonymous):

I don't understand ;o

jigglypuff314 (jigglypuff314):

how about 8/5 = x/20 so 5x = 160

OpenStudy (anonymous):

A.32 Feet ... Yeah that's a bit simpler :-)

jigglypuff314 (jigglypuff314):

lol :P

OpenStudy (anonymous):

Just 2 more! You're a huge help! I'll do the rest on my own after these 2 ;o

jigglypuff314 (jigglypuff314):

gimme a sec...

OpenStudy (anonymous):

Sounds good! :)

jigglypuff314 (jigglypuff314):

pythagorean theorem --> a^2 + b^2 = c^2 the smaller left triangle --> 9^2 + 3^2 = y^2 so y^2 = 90 the smaller right triangle --> 3^2 + x^2 = z^2 so z^2 = 9 + x^2 and then the overall big triangle --> y^2 + z^2 = (9+x)^2 so plug in and FOIL so 90 + 9 + x^2 = x^2 + 18x + 81 subtract x^2 from both sides -x^2 -x^2 so 99 = 18x + 81 solve for x

OpenStudy (anonymous):

x=1 :)

jigglypuff314 (jigglypuff314):

yep :)

OpenStudy (anonymous):

Last one! And thanks again for the help! :)

jigglypuff314 (jigglypuff314):

maybe C

OpenStudy (anonymous):

The shadow one was 24 :/

jigglypuff314 (jigglypuff314):

ahh right... sorry about that :/ I think I had a brain fart like when I had tried re-explaining it so you could understand, I forgot what the question was asking :/
