In a right triangle, the lengths of the two legs are 6 units and 8 units. A circle is inscribed within this triangle. What is the radius of the inscribed circle?
To find the radius of the inscribed circle in a right triangle, we can use the formula:
$$ r = \f\frac{a + b - c}{2} $$
where $r$ is the radius of the inscribed circle, $a$ and $b$ are the lengths of the legs, and $c$ is the length of the hypotenuse.
