OpenStudy (anonymous):
oh okay. the hypotenuse has 3+2s on it. S is your base, and 12 is the height/larger leg
OpenStudy (anonymous):
What will be the equation? 3+2s+s=12?
OpenStudy (anonymous):
Not exactly. You would have to be using the Pythagorean theorem I think. so A^2 + B^2 = C^2. A^2 is 144, B^2 is the same as saying S^2, and C^2 = 4s^2 + 12s + 9
OpenStudy (anonymous):
So entire equation put together: 144 + S^2 = 4s^2 + 12s + 9

Oh wait i'll try to solve
OpenStudy (anonymous):
I got x=9?
OpenStudy (anonymous):
That is what I got
OpenStudy (anonymous):
So the hypotenuse is 21 and shorter leg is 9?
OpenStudy (anonymous):
yes
