To find the hypotenuse of a right triangle, use the following formula:
[tex] c=\sqrt{a^2+b^2} [/tex]
Your a and your b are your legs. Plug them in. In this case, we plug in 7 for both.
[tex] c=\sqrt{7^2+7^2}[/tex]
[tex] c=\sqrt{49+49}[/tex]
[tex] c=\sqrt{98}[/tex]
Your answer would be:
Approximate: 9.9
Exact: [tex]7\sqrt{2}[/tex]
