mathstudent55 · Answer

For a right triangle, you can use the Pythagorean theorem:

$a^2 + b^2 = c^2$

where a and b are the lengths of the legs, and c is the length of the hypotenuse.

mathstudent55 · Answer

Use the formula above and substitute both a and b by 4.
What do you get?

mathstudent55 · Answer

$a^2 + b^2 = c^2$

$4^2 + 4^2 = c^2$

What is 4^2?

anonymous · Answer

32

anonymous · Answer

squared

mathstudent55 · Answer

$4^2 + 4^2 = c^2$

$16 + 16 = c^2$

$c^2 = 32$

Ok so far?

anonymous · Answer

i have to put it in a different form

mathstudent55 · Answer

We are not finished.
Now we need to find c, so we take the square root of both sides.

$c^2 = 32$

$c = \sqrt{32} $

ok?
