  • [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 find the missing side.

Step 2: Identify Variables

Leg a = 5

Leg b = x

Hypotenuse c = 12

Step 3: Solve for x

  1. Substitute:                    5² + x² = 12²
  2. Isolate x term:               x² = 12² - 5²
  3. Exponents:                   x² = 144 - 25
  4. Subtract:                       x² = 119
  5. Isolate x:                       x = √119

Answer:

x= 10.91

Step-by-step explanation:

1. Use the Pythagoreon theorem to solve for x.
