Question

What is the length of an hypotenuse with legs of 7 cm and 24 cm?

Answer 1

If it's a right triangle, use the Pythagorean Theorem. Otherwise, someone else will have to answer. :/

Explanation:

The Pythagorean theorem states that `A^2 +B^2 =C^2` when A and B are the legs of a right triangle and C is the hypotenuse. Re-arranged to solve for the hypotenuse, it looks like this:

`C=sqrt(A^2 +B^2)`

Now we just plug in our values:

`C=sqrt(7^2 +24^2)`

Square the numbers first:

`C=sqrt(49+576)`

Add:

`C=sqrt(625)`

And finally, take the square root:

`C=25`
