Real-time calculations

Step-by-step solving

1. Note Pythagorean Theorem relationship: a² + b² = c²
2. We are solving for the Hypotenuse (c). Formula: c = sqrt(a² + b²)
3. Substitute values: c = sqrt(3² + 4²)
4. Square terms: c = sqrt(9 + 16) = sqrt(25)
5. Extract square root: c = 5

Student-friendly explanations

"The Pythagorean theorem says that if you draw three square boxes on each side of a right-angled triangle, the area of the two smaller boxes combined (a² + b²) is exactly equal to the area of the largest box on the slanted side (c²). Here, solving for the missing side gives a length of **5**!"
