so first find x when given x + 3 = 15

OpenStudy (anonymous):

12

jigglypuff314 (jigglypuff314):

then plug that into 3y - 1 = 2x - 4 to find y

OpenStudy (anonymous):

y=7 :3

jigglypuff314 (jigglypuff314):

yep :)

OpenStudy (anonymous):

Are you ok with proof? That is why weakest subject :/

jigglypuff314 (jigglypuff314):

I took geometry 5 years ago ;) I've forgotten most of the theorem's names and stuff but I should be able to help a little :P

OpenStudy (anonymous):

OMG YOU TOOK GEOMETRY WHEN YOU WERE 11? um wtf

jigglypuff314 (jigglypuff314):

explain's why I'm taking a college course in high school right now ;) (and failing miserably) anyways... the step after the step with the blank has angle 8 having to do with something the blank step's proof is vertical angles what is the vertical angle of <8 ?

OpenStudy (anonymous):

4?

jigglypuff314 (jigglypuff314):

vertical angles are |dw:1385944461013:dw|knowing that, what is the vertical angle of angle 8 ?

OpenStudy (anonymous):

6

jigglypuff314 (jigglypuff314):

yep :) so angle 6 = angle 8

OpenStudy (anonymous):

jigglypuff314 (jigglypuff314):

first use the Pythagorean Theorem to find PN so PN = √(18^2 - 8^2) then LN = 2 * (PN)

OpenStudy (anonymous):

What?

jigglypuff314 (jigglypuff314):

what is √(18^2 - 8^2)

OpenStudy (anonymous):

16.12

jigglypuff314 (jigglypuff314):

then times that by 2

OpenStudy (anonymous):

It cant be 32.24...

jigglypuff314 (jigglypuff314):

hmm... why not?

OpenStudy (anonymous):

PO looks HUGE and it's only 8 :/

jigglypuff314 (jigglypuff314):

the picture is probably not up to scale?

OpenStudy (anonymous):

jigglypuff314 (jigglypuff314):

(360 - (X + Z)) / 2 =

jigglypuff314 (jigglypuff314):

because there has to be total 360 degrees in a quadrilateral angle W = angle Y because of kite properties

jigglypuff314 (jigglypuff314):

(360 - (X + Z)) / 2 = (plug in) (360 - (87+38)) / 2 =

OpenStudy (anonymous):

117.5?

jigglypuff314 (jigglypuff314):

yep :)

OpenStudy (anonymous):

jigglypuff314 (jigglypuff314):

well, the given is about the diagonals therefore the options about "opposite sides" are invalid ...

jigglypuff314 (jigglypuff314):

then between "no" and "yes" I would choose yes... ... ... umm... I think it's the theorem that "If it is a parallelogram, then it's diagonals bisect each other" then the inverse is true.

OpenStudy (anonymous):

jigglypuff314 (jigglypuff314):

it is always a up 5 over 5 or down 5 over 5 to get to the next point... so square...

jigglypuff314 (jigglypuff314):

oh wait... nvm because it is a square it would be all three because a square is a rhombus and rectangle ;)

OpenStudy (anonymous):

You're a HUGE help.

jigglypuff314 (jigglypuff314):

|dw:1385948510442:dw|

OpenStudy (anonymous):

98?

jigglypuff314 (jigglypuff314):

yep :)

OpenStudy (anonymous):

10.50 right?

jigglypuff314 (jigglypuff314):

correct! :D

OpenStudy (anonymous):

jigglypuff314 (jigglypuff314):

distance formula between all the points...

OpenStudy (anonymous):

Oh, I sent you the wrong one ;-; I got that one ;3
