##### Problem 3
 Step 1) Pick a pair of corresponding sides (follow the letters) AB and AD are corresponding based on the letters of the triangle names $$\triangle \color{red}{AB}C$$ ~ $$\triangle \color{red}{AD}E$$ Step 2) Substitute side lengths into proportion $$\frac{AB}{AD} = \frac{40}{30}$$ Step 3) Simplify (if necessary) $$\frac{40}{30}=\frac{4}{3}$$
##### Problem 4

Since AX and AC are corresponding, just set up a proportion and solve:

$\frac{2}{5} = \frac{x}{10} \\ \frac{2 \cdot 10}{5} = x \\ x = 4$
