Trigonometry

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

Step-by-step explanation:

Step 1: Define

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

Step 2: Identify Variables

Leg a = 5

Leg b = 8

Hypotenuse c = x

Step 3: Solve for x

  1. Substitute:                    5² + 8² = x²
  2. Exponents:                   25 + 64 = x²
  3. Add:                              89 = x²
  4. Isolate x:                       √89 = x
  5. Rewrite:                        x = √89
