Answer 1

Do you know the Pythagorean Theorem?

Answer 2

Kinda

Answer 3

a^2+b^2=c^2 ?

Answer 4

It's \[a ^{2}+b ^{2}=c ^{2}\]13=c
12=b
and a=?

Answer 5

So, to find "a", we need to take c^2-b^2=a

Answer 6

Oh okay so that would give me my answer?

Answer 7

\[13^{2}=169\]\[12^{2}=144\]---------\[169-144=25\]\[\sqrt{25}=5\]

Answer 8

So, the bottom of the triangle would be 10, and the other sides are 13 and 13.

13+13+10=?
