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.
