Hypotenuse of 5 and 7
Hypotenuse = √74 ≈ 8.602325
For a right triangle with legs 5 and 7, the hypotenuse c satisfies a² + b² = c²:
5² + 7² = 25 + 49 = 74, so c = √74 ≈ 8.602325 (√74).

Frequently asked questions
What is the hypotenuse of a triangle with legs 5 and 7?
It is √74 ≈ 8.602325 (or √74 in simplified radical form). Using a² + b² = c²: 5² + 7² = 74.
Is 5, 7, … a Pythagorean triple?
No. The hypotenuse √74 is not a whole number, so 5 and 7 do not form a Pythagorean triple with an integer hypotenuse.
