To find the ratio of the side opposite angle \( A \) to the hypotenuse of triangle \( ABC \), we first identify the lengths of the sides of triangle \( ABC \). In triangle \( ABC \):
- Side \( AB = 6 \) (this is one leg),
- Side \( BC = 8 \) (this is the other leg),
- Side \( CA = 10 \) (this is the hypotenuse).
The angle \( A \) is opposite side \( BC \). Therefore, the side opposite angle \( A \) is the length of side \( BC\), which is 8.
Now, to find the ratio of the side opposite angle \( A \) to the hypotenuse, we can express it as follows:
\[ \text{Ratio} = \frac{\text{Opposite side}}{\text{Hypotenuse}} = \frac{BC}{CA} = \frac{8}{10} = \frac{4}{5}. \]
This ratio \( \frac{4}{5} \) indicates the relationship between the opposite side to angle \( A \) and the hypotenuse in triangle \( ABC \).
Now we will identify the corresponding side lengths in triangle \( A'B'C' \). In triangle \( A'B'C' \), the corresponding lengths of the sides are:
- Opposite side \( A' B' = 32\),
- Opposite side \( A' C' = 40\) (the hypotenuse),
- Side \( B' C' = 24\).
To find the corresponding location of point \( A' \) in triangle \( A'B'C' \) using the ratio \( \frac{4}{5}\):
- Let \( x \) be the length of the side opposite angle \( A' \) in triangle \( A'B'C' \). We need to find \( A'B' \) in terms of the hypotenuse \( A' C' \).
- The ratio of the side opposite angle \( A' \) (which corresponds to side \( BC \) in triangle \( ABC \)) to the hypotenuse \( A'C' \) (which corresponds to side \( CA \) in triangle \( ABC \)) gives us:
\[ \frac{A'B'}{A'C'} = \frac{4}{5}. \]
- Given \( A'C' = 40 \), we can find \( A'B' \):
\[ A'B' = \frac{4}{5} \times A'C' = \frac{4}{5} \times 40 = 32. \]
Thus, the side opposite to angle \( A' \) in triangle \( A'B'C' \) (denoted as \( A'B' \)) has been confirmed to be \( 32 \), which indicates that point \( A' \) is located where the side opposite angle \( A' \) and the hypotenuse \( A'C' \) maintains the same ratio \( \frac{4}{5} \).
In summary, point \( A' \) is located based on the ratio \( \frac{BC}{CA} = \frac{4}{5} \) which aligns with the sides \( 32 \) (the opposite side) and \( 40 \) (the hypotenuse) of triangle \( A'B'C' \).
