▼

- The problem requires finding the value of an expression involving trigonometric functions and a square root.
- First, simplify the expression inside the square root: $\sqrt{1 - \sin^2 x}$.
- Use the Pythagorean identity: $\sin^2 x + \cos^2 x = 1$, which implies $1 - \sin^2 x = \cos^2 x$.
- Therefore, $\sqrt{1 - \sin^2 x} = \sqrt{\cos^2 x} = |\cos x|$.
- Since the problem specifies that $x$ is in the interval $(0, \frac{\pi}{2})$, $\cos x$ is positive.
- Thus, $|\cos x| = \cos x$.
- The original expression becomes $\sin x + \cos x$.
- The final answer is $\sin x + \cos x$.
