Question

Make a the subject of a^2+b^2=c^2

Answer 1

a = √(c² - b²)

General Formulas and Concepts:

Pre-Algebra

• Equality Properties

Explanation:

Step 1: Define

a² + b² = c²

Step 2: Rearrange

1. Subtract b² on both sides: a² = c² - b²
2. Square root both sides: a = √(c² - b²)

And we have our final answer!
