To solve for the side length $x$ in this right triangle, we can use the Pythagorean theorem. This theorem states that in a right triangle:

$a^2 + b^2 = c^2$

where $c$ is the hypotenuse (the longest side) and $a$ and $b$ are the other two sides. In this case:

• The hypotenuse $c = 5$
• One leg $b = 4$
• We need to find the other leg $a = x$

Step-by-Step Solution

1. Substitute the values into the formula:

   $x^2 + 4^2 = 5^2$

2. Simplify the squares:

   $x^2 + 16 = 25$

3. Isolate $x^2$ by subtracting 16 from both sides:

   $x^2 = 9$

4. Take the square root of both sides:

   $x = \sqrt{9} = 3$

Answer

The length of $x$ is 3.00, when rounded to the nearest hundredth.
