To find the length of the hypotenuse of a right triangle that has its vertices at the origin, on the unit circle, and on the x-axis inside the unit circle, we first need to identify the coordinates of these points.

1. **The Origin:** The first vertex is at the point (0, 0).

2. **On the Unit Circle:** The unit circle is given by the equation \( x^2 + y^2 = 1 \). For simplicity, let's denote a point on the unit circle as \( (x, y) \) where \( x = \cos(\theta) \) and \( y = \sin(\theta) \), for some angle \( \theta \).

3. **On the X-axis Inside the Unit Circle:** Let's denote the point on the x-axis as \( (a, 0) \), where \( -1 < a < 1 \).

Now we form a right triangle from these three points:
- Point 1: \( (0, 0) \) (the origin)
- Point 2: \( (\cos(\theta), \sin(\theta)) \) (on the unit circle)
- Point 3: \( (a, 0) \) (on the x-axis)

The hypotenuse of the triangle is the segment between points \( (0, 0) \) and \( (\cos(\theta), \sin(\theta)) \).

To find the length of the hypotenuse:
\[
\text{Length of hypotenuse} = \sqrt{(\cos(\theta) - 0)^2 + (\sin(\theta) - 0)^2} = \sqrt{\cos^2(\theta) + \sin^2(\theta)}
\]

By the Pythagorean identity, we know:
\[
\cos^2(\theta) + \sin^2(\theta) = 1
\]

Thus, we have:
\[
\text{Length of hypotenuse} = \sqrt{1} = 1
\]

Therefore, the length of the hypotenuse of the triangle is \( \boxed{1} \).
