\begin{cases}x + y  = 40 \\  \frac{x}{20} +  \frac{y}{4}   = 6\end{cases} \\ \Leftrightarrow \begin{cases} x + y = 40\\x + 5y = 120 \end{cases} \\ \Leftrightarrow \begin{cases} x + y = 40\\ 4y = 80\end{cases} \\ \Leftrightarrow \begin{cases}x  = 20 \\ y = 20\end{cases}

△XYZ was reflected over a vertical line, then dilated by a scale factor of , resulting in △X'Y'Z'. Which must be true of the two
Igoryamba

Answer:

correct option is △XYZ ~ △X'Y'Z'.

Step-by-step explanation:

since ΔXYZ is dilated by some scale factor so, the resulting triangle can not be congruent to the ΔXYZ. so option 2 is wrong.

as we have explained that the two triangles are not congruent then it's sides and angles also can't be congruent so, option 3 is also incorrect.

As we don't know by what factor the triangle XYZ is dilated so we can't say anything about correctness of option 4 and 5.

ΔXYZ  was reflected over a vertical line and then dilated so the resulting ΔX'Y'Z' is similar to ΔXYZ.

i.e., △XYZ ~ △X'Y'Z'.
