Trigonometry

[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: Define

a = 7

b = 4

Step 2: Solve for c

  1. Substitute [PT]:                         7² + 4² = c²
  2. Evaluate exponents:                49 + 16 = c²
  3. Add:                                           65 = c²
  4. Isolate c:                                   √65 = c
  5. Evaluate radical:                      8.06226 = c
  6. Rewrite:                                    c = 8.06226
  7. Round:                                      c ≈ 8.06
