Question

I need help with finding the length to this problem please?

Answer 1

Let:

k = Constant of proportionality

Since the triangles are similar, we can conclude:

`\begin{gathered} 2.5k=5 \\ k=(5)/(2.5) \\ k=2 \end{gathered}`

Therefore:

`\begin{gathered} kx=4 \\ 2x=4 \\ x=(4)/(2) \\ x=2 \end{gathered}`

Answer:

2
