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

  • a is one leg
  • b is another leg
  • c is hypotenuse

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

a = 19

b = <em>x</em>

c = 21

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [PT]:                    19² + x² = 21²
  2. Isolate <em>x</em> term:                      x² = 21² - 19²
  3. Exponents:                           x² = 441 - 361
  4. Subtract:                               x² = 80
  5. Isolate <em>x</em>:                               x = √80
  6. Simplify:                                x = 4√5
