Step-by-step explanation:
To find the missing lengths of a triangle, we must use pythagorean theorem. I'll put each part in steps so you can easily follow.
<h3>
Step 1: Set Up the Equation</h3>

Note: c is the longest side of the triangle, the hypotenuse and a and b are the other two sides.
<h3>Step 2: Fill in Given Values</h3>

<h3>Step 3: Multiply</h3>

<h3>Step 4: Subtract</h3>

<h3>Step 5: Unsquare b</h3>

b = about 1.6
<h3>Step 6: Find the Chord</h3>

about 3.1 feet
<h3>Step 7: Check</h3>
1.96 + 2.45 = 4.41
4.41 = 4.41 ✔
<h3>Step 8: Answer</h3>
x = about 3.1 feet
