Question

Write the scale factor

Answer 1

Let:

`\begin{gathered} FO\cdot k=QK \\ \end{gathered}`

Where:

k = scale factor

so:

`\begin{gathered} 18k=24 \\ k=(24)/(18) \\ k=(4)/(3) \end{gathered}`

now, we can find y and x:

`\begin{gathered} (4)/(3)\cdot x=28 \\ x=(28\cdot3)/(4) \\ x=21 \end{gathered}`
`\begin{gathered} 15\cdot(4)/(3)=y \\ 20=y \end{gathered}`
