hint : a square has all right angles
OpenStudy (anonymous):
?
OpenStudy (jdoe0001):
grab the "y" equations and make them equal, because both legs are equal, then solve for "y"
OpenStudy (anonymous):
5y-4=2y+23

get ganeshie8 's hint and make that equal to what a right-angle is :), then solve for "x"
OpenStudy (anonymous):
5y-4=90 2y+23=90
OpenStudy (anonymous):
like that?
OpenStudy (jdoe0001):
5y-4 = 2y+23

i thought so u would do that lol

hahah.x) so i was wrong?
OpenStudy (jdoe0001):
left length = right length
OpenStudy (anonymous):
confused..
OpenStudy (jdoe0001):
"x equation" degrees = "right-angle" degreess
OpenStudy (anonymous):
so its like this? 5y-4 = 2y+23

look at your picture, is the left-line equal to the right-line?
OpenStudy (anonymous):
ok?
OpenStudy (jdoe0001):
is a square, so all sides are equal, so
OpenStudy (jdoe0001):
the equation are just the length
OpenStudy (anonymous):
hmm..?

so, if both lines are equal, so are their equations
OpenStudy (anonymous):
D: Your confusing me.
OpenStudy (jdoe0001):
I wish I had 2 chicken to use for comparison but anyway

draw a picture??|dw:1371588888864:dw|
