  • Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

Step 1: Define

Leg a = x

Leg b = 64

Hypotenuse c = 80

Step 2: Solve for x

  1. Substitute:                    x² + 64² = 80²
  2. Isolate x term:              x² = 80² - 64²
  3. Exponents:                   x² = 6400 - 4096
  4. Subtract:                       x² = 2304
  5. Isolate x:                       x = √2304
  6. Evaluate:                       x = 48
