Question

What is the length of the hypotenuse of a right triangle if the two other sides are of lengths 3 and 5?

Answer 1

`36`

Explanation:

By the Pythagorean theorem, the length of the hypotenuse `c` of a right triangle with legs of length `a` and `b` is given by

`c^2 = a^2 + b^2`

Applying this here, we get

`c^2 = 3^2 + 5^2 = 9 + 25 = 36`

Thus `c = sqrt(36) = 6`
