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

Step-by-step explanation:

Step 1: Identify Variables

Leg a = x

Leg b = 2

Hypotenuse c = 7

Step 2: Solve for x

  1. Substitute [PT]:                    x² + 2² = 7²
  2. Isolate x term:                      x² = 7² - 2²
  3. Exponents:                          x² = 49 - 4
  4. Subtract:                              x² = 45
  5. Isolate x:                              x = 3√5
  6. Evaluate:                              x = 6.7082
  7. Round:                                 x ≈ 6.7
