One job, done clearly: enter the two legs of a right triangle and get the hypotenuse via c = √(a² + b²), with each substitution shown.
Direct hypotenuse length from the two legs, step by step.
c = √(a² + b²)
| Symbol | Meaning |
|---|---|
| a, b | The two legs |
| c | Hypotenuse |
Legs 6 and 8 → c = √(36 + 64) = √100 = 10.
