Explanation:

Step1: Recall similarity - ratio property

For similar triangles, the ratios of corresponding sides are equal. Let's take problem 13 as an example. If $\triangle MNO\sim\triangle PQR$, then $\frac{MN}{PQ}=\frac{NO}{QR}=\frac{MO}{PR}$.

Step2: Identify corresponding sides

In problem 13, assume the side - length of $MN = 6$, $NO = 13$, and $QR = 44$. We want to find $PQ$. The ratio of corresponding sides gives us $\frac{MN}{PQ}=\frac{NO}{QR}$.

Step3: Set up and solve the proportion

Substitute the known values into the proportion: $\frac{6}{PQ}=\frac{13}{44}$. Cross - multiply to get $13\times PQ=6\times44$. Then $PQ=\frac{6\times44}{13}=\frac{264}{13}\approx20.3$.

For other problems (14 - 16), the same process is followed:

  1. Identify the similar triangles and the corresponding sides.
  2. Set up a proportion based on the ratio of corresponding sides.
  3. Cross - multiply and solve for the unknown side - length.

Answer:

For problem 13: $PQ\approx20.3$. For other problems, follow the above steps to find the lengths of the required sides.
