Hypotenuse of 3 and 8
Hypotenuse = √73 ≈ 8.544004
For a right triangle with legs 3 and 8, the hypotenuse c satisfies a² + b² = c²:
3² + 8² = 9 + 64 = 73, so c = √73 ≈ 8.544004 (√73).

Frequently asked questions
What is the hypotenuse of a triangle with legs 3 and 8?
It is √73 ≈ 8.544004 (or √73 in simplified radical form). Using a² + b² = c²: 3² + 8² = 73.
Is 3, 8, … a Pythagorean triple?
No. The hypotenuse √73 is not a whole number, so 3 and 8 do not form a Pythagorean triple with an integer hypotenuse.
