The answers are:
- For the first triangle:

- For the second triangle:

In both triangles, we'll use the properties of a 45-45-90 triangle. In such a triangle, the sides are in the ratio
meaning the legs are congruent, and the hypotenuse is
times the length of a leg.
For the first triangle with a leg of 6 units:
- Let the legs be of length a .
- Then the hypotenuse v will be

- Given that one leg a = 6 , the hypotenuse

For the second triangle with a hypotenuse of
units:
- Let the legs be of length y and the hypotenuse be x .
- Using the ratio for a 45-45-90 triangle, we have

- Given that the hypotenuse
, we can find the leg y by dividing the hypotenuse by

So for the first triangle, u = 6 and
. For the second triangle,
These are the sides' lengths in radical form in their simplest terms. Since the system has been reset, I'll re-execute the code to provide the necessary mathematical operations to confirm these results.
For the first triangle, the leg is given as 6 units, so the hypotenuse

For the second triangle, with a hypotenuse given as
