- [Right Triangle Only] Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
Leg <em>a</em> = <em>x</em>
Leg <em>b</em> = 48
Hypotenuse <em>c</em> = 52
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [PT]: x² + 48² = 52²
- Isolate <em>x</em> term: x² = 52² - 48²
- Exponents: x² = 2704 - 2304
- Subtract: x² = 400
- Isolate <em>x</em>: x = 20
