Thank you

**Lena**, Tuesday, March 29, 2011 at 12:42amYou want to use Pythagorean theory here. So a^2 + b^2 = c^2. a and b would be the 2 side length and then solve for c. Do you think you can take it from here? If you tell me what you got as a answer I can figure it out and let you know what I got.

To be honest with you, I don't know how to do any of this; however, what i do is figure out the answer and how it was solved once i have everything on the table. I look at the answer and the steps that were made to teach myself. I really appreciate your help in this. Thank you.

**Lena**, Tuesday, March 29, 2011 at 1:30amOk so what you would do in this scenario is fill in the sides for a and b.

10^2 + 7^2 = c^2

( c is the diagonal AKA the hypotenuse)

100 + 49 = c^2

149 = c^2

sq root of 149 = c

12.21 = c

(this # is rounded)

But that's what your diagonal should be.
