Question

If the length of the legs in a right triangle are 7 and 8, what is the approximate length of the hypotenuse?

Answer 1

do you know the pythagorean theorem ?
\[a^2 + b^2 = c^2\]
where a and b are the legs and c is the hypotenuse

Answer 2

Just set up an equation using the pythagorean theorem i like this version of it to find the hypotenuse:\[c = \sqrt{a^2+b^2}\]
where c is the hypotenuse and a and b are the legs.
so:
\[c = \sqrt{7^2+8^2}\]
Simplify:\[c=\sqrt{49+64}\]
becomes:\[\sqrt{113}=c\]
The hypotenuse is:
\[\sqrt{113}\]
