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

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

OMG
YOU TOOK GEOMETRY WHEN YOU WERE 11? um wtf

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

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

then times that by 2
OpenStudy (anonymous):
It cant be 32.24...
jigglypuff314 (jigglypuff314):
hmm... why not?

PO looks HUGE and it's only 8 :/

(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

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.

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 ;)
