  • Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

Step 1: Define

Leg a = x

Leg b = 7

Hypotenuse c = 10

Step 2: Solve for x

  1. Substitute:                    x² + 7² = 10²
  2. Isolate x term:              x² = 10² - 7²
  3. Exponents:                   x² = 100 - 49
  4. Subtract:                       x² = 51
  5. Isolate x:                       x = √51
