7.3

Step-by-step explanation

here we have a rigth triangle, so we can use the Pythagoren theorem ,it states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse

Step 1

Let


\begin{gathered} \text{side}1\text{ = 6.4} \\ \text{side}2=3.5 \\ \text{hypotenuse = h} \end{gathered}

so, the P.T says


(\text{side}1)^2+(side2)^2=(hypotenuse)^2

replace


\begin{gathered} 6.4^2+3.5^2=h^2 \\ 53.21=h^2 \\ \text{square root in both sides} \\ √(53.21)=√(h^2) \\ 7.29=h \\ \text{rounded} \\ 7.3=h \end{gathered}

so, the answer is

7.3

I hope this helps you
