Answer:
s = 8 units
Explanation:
In a 45-45-90 triangle (which this triangle is), you can find the legs by dividing the hypotenuse by the square root of 2, and you can find the hypotenuse by multiplying one of the (equal) leg lengths by the square root of 2.
Knowing this, you can find the side length s by dividing the hypotenuse by
.
The length of s is 8 units.
