Trigonometry

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

Explanation:

Step 1: Define

We have a right triangle. We can use PT to solve for the missing side length.

Step 2: Identify Variables

Leg a = 5

Leg b = x

Hypotenuse c = √72

Step 3: Solve for x

1. Substitute [PT]: 5² + x² = (√72)²
2. Exponents: 25 + x² = 72
3. Isolate x term: x² = 47
4. Isolate x: x = √47
