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

Step-by-step explanation:

<u>Step 1: Define</u>

We are given a right triangle. We can use PT to solve for the missing length.

<u>Step 2: Identify Variables</u>

Leg <em>a</em> = 12

Leg <em>b</em> = <em>x</em>

Hypotenuse <em>c</em> = 20

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Substitute:                    12² + x² = 20²
  2. Isolate <em>x</em> term:              x² = 20² - 12²
  3. Exponents:                   x² = 400 - 144
  4. Subtract:                       x² = 256
  5. Isolate <em>x</em>:                       x = 16
