$$r^{2} + p^{2} = q^{2}$$

You should know the pytharogean theorem by now based on the amount of time you're around here lol.

anonymous · Answer

lol  nope

ipwnbunnies · Answer

You don't know the Pythagorean Theorem at all?

anonymous · Answer

I do but its confusing I don't know how to do it

ipwnbunnies · Answer

Ok, bear with me, it only applies to right triangles. Right triangles are the triangles with 90 degree angles.

ok

ipwnbunnies · Answer

So, what the theorem is getting at is that the square of the shortest side + the square of the longer side = the square of the longest side

ipwnbunnies · Answer

a*a + b*b = c*c

anonymous · Answer

yeah I get that part

ipwnbunnies · Answer

Good, so let's put it in the terms of your problem:
p*p + r*r = q*q

anonymous · Answer

yeah but don't we fill in the numbers

ipwnbunnies · Answer

We are given the length of the longest side, q, and the length of the middle side, r. Solve for p.

ipwnbunnies · Answer

Yeah, we're getting to the numbers. Just follow my instructions and solve for p in the pythagorean theorem.
