Question

What's the length of the hypotenuse of a right triangle if the length of one leg is 7 units and the length of the other leg is 14 units?

Answer 1

The hypotenuse is

`7\sqrt[]{5}=15.65`

Explanation:

In this case we can calculate the value of the hypotenuse by means of the Pythagorean theorem.

`\begin{gathered} h^2=a^2+b^2 \\ a=7 \\ b=14 \end{gathered}`

replacing

`\begin{gathered} h^2=7^2+14^2 \\ h^2=49+196 \\ h=\sqrt[]{245} \\ h=7\sqrt[]{5}=15.65 \end{gathered}`
