Answer:
AC ≈ 7.3
Step-by-step explanation:
Corresponding sides of similar triangles are proportional.
AC/BC = DF/EF
AC/18 = 15/37 . . . . fill in the given values
AC = 18(15/37) . . . multiply by 18
AC ≈ 7.3
no way dude really? thats so cool

Length of each side of each of these three equilateral triangle is :
Solution is in attachment ~
3.14=7x-2y
move 7x to the other side
sign changes from +7x to -7x
3.14-7x=7x-7x-2y
3.14-7x=-2y
Divide both sides by -2
3.14/-2-7x/-2=-2y/-2
3.14/-2=-1.57
-7x/-2=7x/2
Answer:
y=-1.57+7x/2
