Find the length of the third side. If necessary, round to the nearest tenth.47

Given a right angle triangle
The length of the legs are 4 and 7
we will find the hypotenuse using the Pythagorean theorem
So,
[tex]\begin{gathered} h^2=7^2+4^2=49+16=65 \\ h=\sqrt[]{65}\approx8.062 \end{gathered}[/tex]Rounding to the nearest tenth
So, the answer is the length of the third side = 8.1
