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

Step-by-step explanation:

Step 1: Define

Leg a = 9

Leg b = 40

Hypotenuse c = d

Step 2: Solve for d

  1. Substitute [PT]:                    9² + 40² = d²
  2. Exponents:                           81 + 1600 = d²
  3. Add:                                     1681 = d²
  4. Isolate d:                              41 = d
  5. Rewrite:                                d = 41
