Answer 1

This is really easy, where are you stuck?

Answer 2

Anyways, (3,4,5) is a Pythagorean triple.

Answer 3

Notice how it forms a right-angled triangle. We can find the value by using Pythagorean theorem. Notice that the required side is the Hypotenuse.

\(\Large \color{purple}{\rightarrow ?^2 = 3^2 + 4^2 }\)
\(\Large \color{purple}{\rightarrow ?^2 = 9 + 16 }\)
\(\Large \color{purple}{\rightarrow ?^2 = 25 }\)
\(\Large \color{purple}{\rightarrow ? = \sqrt{25} }\)
\(\Large \color{purple}{\rightarrow ? = 5 }\)

\( \checkmark \)
