Answer:

Explanation:

Since these two are similar triangles, we can set up a proportion, and solve for x.

x is to 2, as x+x+2 is to 3+2 :


(x)/(2)=(2x+2)/(5)

Now solve for x, by cross multiplying

x*5=2(2x+2)

5x=4x+4

Subtract by 4x on both sides

x=4

Set up a ratio to see if the answer's correct:


(4)/(2)=(6)/(3)


2=2

Since the ratios are equal, x=4.
