To find the ratio of the side opposite angle A to the hypotenuse in triangle ABC, we identify the side lengths: AB = 6 (opposite angle A), AC = 10 (hypotenuse). The ratio is calculated as the length of the opposite side divided by the length of the hypotenuse, which gives us 6/10 or simplified to 3/5.
In the second triangle with corresponding sides of 32 (opposite angle A'), 40 (hypotenuse), and 24 (the other side), we can use this ratio to locate point A'. Since the ratio 3/5 must hold, and the hypotenuse is 40, we find the side opposite A' as (3/5) * 40 = 24. Therefore, point A' is located opposite the side with length 24 in the second right triangle, which corresponds to the side opposite angle A.
