Using the Pythagorean theorem, we can find the length of the other leg of the triangle.
Let the length of the other leg be x.
According to the Pythagorean theorem, x^2 + 11^2 = 22^2.
Simplifying this equation, we have x^2 + 121 = 484.
Subtracting 121 from both sides, we get x^2 = 363.
Taking the square root of both sides, we find that x = √363.
Rounding to two decimal places, x ≈ 19.06.
Therefore, the length of the other leg is approximately 19.06.
