What is the ninth of the missing side of the triangle rounds the nearest 10th necessary. The missing side is about blank cm

Given:
Base =3.5 cm
Perpendicular = 6.4 cm
Find: Hypotenuse
Sol:
Use Pythagoras theorem.
[tex]\text{ Hypotenuse}^2=Base^2+perpendicular^2[/tex][tex]\begin{gathered} \text{ Hypotenuse}^2=3.5^2+6.4^2 \\ \text{ Hypotenuse}^2=12.25+40.96 \\ \text{ Hypotenuse}^2=53.21 \\ \text{ Hypotenuse=}\sqrt[]{53.21} \\ \text{ Hypotenuse=7.2945} \end{gathered}[/tex]So the hypotenuse is 7.3
