anonymous · Answer

I think the answer is 25 B or maybe A 10?

johnweldon1993 · Answer

ahh...that's very nice of you :)

the pythagorean theorem states

A² + B² = C²

C is your hypotenuse (longest side)

you have THAT....and you have 1 side....so

10² + B² = 35²

you want B so

B = √(35²-10²)

That would be?
