Triangle ABC is similar to triangle XYZ. Side AB measures 2, side BC measures x + 5, side CA measures x + 7, side XY measures 4

Firlakuza [10]

Answer:

$x=8$

Step-by-step explanation:

In similar triangles, corresponding sides' ratio are equal.

Side AB corresponds to Side XY
Side BC corresponds to Side YZ
Side CA corresponds to Side ZX

We can set up a ratio of $\frac{SideAB}{Side XY}=\frac{SideCA}{Side ZX}$

Hence, we can write (and solve):

$\frac{Side AB}{Side XY}=\frac{Side CA}{SideZX}\\\frac{2}{4}=\frac{x+7}{4x-2}\\2(4x-2)=4(x+7)\\8x-4=4x+28\\8x-4x=28+4\\4x=32\\x=\frac{32}{4}=8$

So, x = 8
