Hi there! :)
Since we are looking for the hypotenuse, we will use the Pythagorean theorem.
Which is:
[tex]a^2+b^2=c^2[/tex]
We know the values of a and b so let's plug them in
[tex]3^2+10^2=c^2[/tex]
[tex]9+100=c^2[/tex]
[tex]109=c^2[/tex]
Square root both sides to cancel out the root
[tex] \sqrt{109} = \sqrt{c^2} [/tex]
Final answer:
C=10.44
