Line segment AC is parallel to DE.. Solve for x. x = 27 x = 1 x = 25 x = 3

OpenStudy (lopezking1):

OpenStudy (anonymous):

Because : \[AC//DE\] then : \[\frac{BE}{BC}=\frac{BD}{BA}\] So : \[\frac{2}{x+2}=\frac{6}{15}\] Solve the equation to get x

OpenStudy (lopezking1):

okay i got this

OpenStudy (ivettef365):

but BA = x+2+2

OpenStudy (anonymous):

Yes ! I have a mistake : \[BA=x+2+2=x+4\] @lopezking1

OpenStudy (ivettef365):

so it would be 2/x+4

OpenStudy (lopezking1):

So how would it look like in a proportion 6(x+4)=32?

OpenStudy (ivettef365):

the correct form is 6(x+4) = 30

OpenStudy (lopezking1):

x=1?

OpenStudy (ivettef365):

correct

OpenStudy (lopezking1):

my question is where did the 15 come from and what happen to the 9

OpenStudy (ivettef365):

measure of BC = 9 + 6

OpenStudy (lopezking1):

ohhhh okay thanks

OpenStudy (ivettef365):

yw :)
