To find the unknown side of the right triangle, we can use the Pythagorean theorem, which states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Let's denote the unknown side as x:
8^2 + x^2 = 20^2
64 + x^2 = 400
x^2 = 336
x = √336
x ≈ 18.33 ft
Therefore, the unknown side of the right triangle is approximately 18.33 ft.
