- [Right Triangles Only] Pythagorean Theorem: a² + b² = c²
Explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use PT to solve for the missing length.
<u>Step 2: Identify Variables</u>
Leg <em>a</em> = 55 ft
Leg <em>b</em> = <em>x</em> ft
Hypotenuse <em>c</em> = 80 ft
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitute: 55² + x² = 80²
- Isolate <em>x</em> term: x² = 80² - 55²
- Exponents: x² = 6400 - 3025
- Subtract: x² = 3375
- Isolate <em>x</em>: x = √3375
- Simplify: x = 15√15
- Evaluate: x = 58.0948
- Round: x ≈ 58
