\[AC= \frac{ 3y }{ 5 }\]
OpenStudy (anonymous):
\[BD=3y-4\]
OpenStudy (anonymous):
ar ac and bd the diagonals?
OpenStudy (anonymous):
I guess so
OpenStudy (anonymous):
@Ahmad1 from her previous example the lines she gave are the diagonals.

yes they are the diagonals
OpenStudy (anonymous):
well u gave me the wrong answer last time so obviously u don't know how to solve the problem
OpenStudy (anonymous):
okay then the lengths must be equal
OpenStudy (anonymous):
(3y)/5=3y-4
OpenStudy (anonymous):
yes and ive tied the problem but I get the wrong answers

OpenStudy (anonymous):
\[3y/5=3y-4 \rightarrow 3y=15y-20\rightarrow 12y=20\rightarrow y=5/3\]
OpenStudy (anonymous):
but remeber, you want the length of the diagonal we say 3/5*5/3=1
OpenStudy (anonymous):
I don't undetsand
OpenStudy (anonymous):
ahmad is right :) now you use 5/3 to plug into either side of the equation

idk how
OpenStudy (anonymous):
just equalized the length you gave , and find y ,then sub in any equation to find the value of the diagonal
OpenStudy (jdoe0001):
"ahmad is right "
unless he needs to make a left-turn
although 3 left-turns make a right-one
OpenStudy (anonymous):
but remeber, you want the length of the diagonal we say 3/5*5/3=1
OpenStudy (anonymous):
ummmmmm................
