130 degrees because x would be 60. 60-10 would be 50 which would make both angles add up to 180.

Answer:

Step-by-step explanation:

(-3,-3) ; (8,-3)

$Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-3-[-3]}{8-[-3]}\\\\=\frac{-3+3}{8+3}\\\\=0$

Slope = 0. so, the line is parallel to x-axis

Let's look at the corresponding ratios:

$\frac{AB}{ED}=\frac{24}{30}=\frac{4}{5}\\\frac{BC}{DC}=\frac{16}{20}=\frac{4}{5}\\\frac{AC}{EC}=\frac{21}{28}=\frac{3}{4}\\$

And we see that the three aren't equal.

Hence, $\Delta ABC$ and $\Delta EDC$ are not similar.
