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

IRISSAK [1]

Given a right angle triangle

The length of the legs are 4 and 7

we will find the hypotenuse using the Pythagorean theorem

So,

$\begin{gathered} h^2=7^2+4^2=49+16=65 \\ h=\sqrt[]{65}\approx8.062 \end{gathered}$

Rounding to the nearest tenth

So, the answer is the length of the third side = 8.1
