Given That Abc Def Solve For X
Solve ABC ~ DEF to x? 3
From ABC ~ DEF you know that AB / DE = BC / EF = AC / DF. That is, if the length from A to B is divided by the length from D to E, then DE is the same ratio on the other side.
You can tell from the picture:
AB = 35
BC = 42
CA = 49
SD = 5
EF = x
From what I said, you know AB / DE = BC / EF.
When entering the value assigned to you, you can write:
AB / DE = BC / EF == 35/5 = 42 / x
Using the cross product, which is multiplied by both sides x and 5, you can simplify the equation like this:
35 * x = 42 * 5
Then divide both sides by 35 to get only x on the left:
x = 42 * 5/35
This is your answer. Just keep it simple and you will get a number. Yellow who helped and now you understand that we have to ask this question :)
There are so many good answers.
