Answer:

3. √74

Step-by-step explanation:

By the Pythagorean theorem, the length of the hypotenuse can be calculated as:


c=\sqrt[]{a^2+b^2}

Where c is the hypotenuse and a and b are the lengths of the legs.

So, replacing a by 5 and b by 7, we get:


\begin{gathered} c=\sqrt[]{5^2+7^2} \\ c=\sqrt[]{25+49} \\ c=\sqrt[]{74} \end{gathered}

Therefore, the answer is 3. √74
