Hypotenuse of 7 and 8

Hypotenuse = √113 ≈ 10.630146

For a right triangle with legs 7 and 8, the hypotenuse c satisfies a² + b² = c²:

7² + 8² = 49 + 64 = 113, so c = √113 ≈ 10.630146 (√113).

Frequently asked questions

What is the hypotenuse of a triangle with legs 7 and 8?

It is √113 ≈ 10.630146 (or √113 in simplified radical form). Using a² + b² = c²: 7² + 8² = 113.

Is 7, 8, … a Pythagorean triple?

No. The hypotenuse √113 is not a whole number, so 7 and 8 do not form a Pythagorean triple with an integer hypotenuse.
