Hey Guys,
For #25)
I am dealing with proportionals here with this problem and I don't know how to get the answer to this one.
I tried 10/8 = 4/x
AC/DE = AD/DB
I ended up getting x = 3.2 but the answer is 16
.
I have an idea that will get me 16 but... I honestly don't know if it's right
so I set up the equation as 10/4 = x/8 which gets me x =20
then I plug in 20 into x because DB = AB - AD and I get 20-4 = 16
But if I plug in numbers like this, I don't understand why I should set it up as AC / AD = DE / DB.
