The hypotenuse is 11.4 cm long
Step-by-step explanation:
We have to find the hypotenuse so the other sides are:
[tex]Perpendicular = P = 7\ cm\\Base = B = 9\ cm\\[/tex]
Pythagoras theorem will be used to find the length of Hypotenuse
[tex]H^2=P^2+B^2\\[/tex]
Putting values
[tex]H^2=(7)^2+(9)^2\\H^2=49+81\\H^2=130[/tex]
Taking square Root on Both sides
[tex]\sqrt{H^2}=\sqrt{130}\\H=11.40[/tex]
Rounding off to the nearest tenth
[tex]H=11.4\ cm[/tex]
Hence,
The hypotenuse is 11.4 cm long
