  • [Right Triangles Only] Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

Step 1: Identify Variables

Leg a = 12

Leg b = x

Hypotenuse c = 17

Step 2: Solve for x

  1. Substitute [PT]:                     12² + x² = 17²
  2. Isolate x term:                       x² = 17² - 12²
  3. Exponents:                            x² = 289 - 144
  4. Subtract:                                x² = 145
  5. Isolate x:                                x = √145
