Answer:

AB = 9.4

Explanation:

The Pythagoras theorem says that if we have a triangle of side lengths a, b and hypotenuse c is given by


a^2+b^2=c^2

Now in our case, a = 6 and b = 7.2; therefore,


6^2+7.2^2=c^2
\rightarrow87.84=c^2

Taking the square root of both sides gives


c=\sqrt[]{87.84}
c=9.372

rounding to the nearest tenth gives


\boxed{c=9.4.}

which is our answer!
