Hypotenuse of 3 and 10

Hypotenuse = √109 ≈ 10.440307

For a right triangle with legs 3 and 10, the hypotenuse c satisfies a² + b² = c²:

3² + 10² = 9 + 100 = 109, so c = √109 ≈ 10.440307 (√109).

Frequently asked questions

What is the hypotenuse of a triangle with legs 3 and 10?

It is √109 ≈ 10.440307 (or √109 in simplified radical form). Using a² + b² = c²: 3² + 10² = 109.

Is 3, 10, … a Pythagorean triple?

No. The hypotenuse √109 is not a whole number, so 3 and 10 do not form a Pythagorean triple with an integer hypotenuse.
