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

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

Step-by-step explanation:

Step 1: Identify

a = 68

b = 51

Step 2: Solve for c

  1. Substitute [PT]:                     68² + 51² =  c²
  2. Exponents:                           4624 + 2601 = c²
  3. Add:                                      7225 = c²
  4. Isolate c:                               85 = c
  5. Rewrite:                                c = 85
