Hypotenuse of 3 and 7
Hypotenuse = √58 ≈ 7.615773
For a right triangle with legs 3 and 7, the hypotenuse c satisfies a² + b² = c²:
3² + 7² = 9 + 49 = 58, so c = √58 ≈ 7.615773 (√58).

Frequently asked questions
What is the hypotenuse of a triangle with legs 3 and 7?
It is √58 ≈ 7.615773 (or √58 in simplified radical form). Using a² + b² = c²: 3² + 7² = 58.
Is 3, 7, … a Pythagorean triple?
No. The hypotenuse √58 is not a whole number, so 3 and 7 do not form a Pythagorean triple with an integer hypotenuse.
