Answer:

x=3.6

Explanation:

The triangles are similar meaning they are proportional, think like a ratio. So the one side is 1 and its proportional side is 20. That means you take a side of the small triangle and multiply by 20 to get the corresponding side on the large triangle. So, the small side x-3, multiply it by 20 to get the larger side.

20(x-3)=4x-2

20x-60=4x-2

16x=58

x=3.6
