The length of the hypotenuse of each right triangle is how many inches.?

PLEASE ANSWER THIS IS IMPORTANT

In order to find out what the hypotenuse of a right triangle is, you need to use the Pythagorean Theorem:

a^2 + b^2 = c^2

In this equation the a and b stand for the length of the legs of the triangle. The c stands for the hypotenuse. Here's an example on how to solve it:

Say you have a right triangle. The two sides are 3 inches and 4 inches. You need to figure out the hypotenuse, so here's what you have to do:

1) Plug in your numbers to the equation.

     (3)^2 + (4)^2 = c^2

2) Square the 3 and the 4

     9 + 16 = c^2

3) Add the 9 and the 16

     25 = c^2

4) Square root both sides to get c by itself

     5 = c

Now that you have c, you have the hypotenuse!
