Answer 2

Halp

Answer 3

sqrt( 13^2 - 12^2 )

Answer 4

Could you explain further? The possible answers are:
A. 1
B. 17.7
C. 5
D. 1

Answer 5

I know how to use the Pythagorean Theorem (A^2 + B^2 = C^2), but I don't know how to get a leg's distance based off of the hypotenuse and another leg.

Answer 6

Well, what's 13^2?

And what's 12^2?

And what's the difference between them?

Answer 7

If the hypotenuse^2 = side1^2 + side2^2, then side2^2 would be hypotenuse^2 - side1^2

Answer 8

13^2 = 169
12^2 = 144
Would the answer be 25?

Answer 9

I know that isn't in the options. That's what I got.

Answer 10

Close...

25 is the answer squared.

What we're after is the square root of 25, and THAT will be your answer! :-)

Answer 11

Thank you! I understand the process now.

Answer 12

Square root of 25 is 5. Heheh.

Answer 13

Excellent!! Glad I could help!

And thank you! :-)

Answer 14

No thank you, good sir. Have a fantastic day.
