Question

I need to find the values of x and y. The polygons are similar but not drawn to scale.

Answer 1

Since we are told that the polygons are similar, then we will determine the values of x and y as follows:

x:

`\begin{gathered} (x+2)/(3)=(10)/(2)\Rightarrow(x+2)/(3)=5 \\ \\ \Rightarrow x+2=15\Rightarrow x=13 \end{gathered}`

y:

`\begin{gathered} (y-1)/(20)=(2)/(10)\Rightarrow(y-1)/(20)=(1)/(5) \\ \\ \Rightarrow y-1=4\Rightarrow y=5 \end{gathered}`

So, the values are x = 13 and y =5. [Option B]
