    alright, we can see from the drawing that AE + FB + DC = 24, which is the length of the bottom, right? first off, we need to find the length of AE from the diagram we can see that AE and FB are equal, so our equation becomes 2*(AE) + DC = 24 DC = 12, so 2*(AE) + 12 = 24 2*(AE) = 12 AE = 6, but we're not done yet

    according to the Pythagorean theorem, C^2 = 8^2 + 6^2 solve for C

    ok what ur going to do is think a+b but you are left with de and dc but you have to think what would u do? add subtract what i was thinking to subtract the AB to the DC so what ur going to do is 24-12=12 so i was thinking 8 is not a answer cause what would u do with 8? 12-8-=4 so ur answer is C for the remainder of 8 so C=12 is ur answer

    C^2 = 8^2 + 6^2 C is clearly 10, not 12...

    C^2 = 8^2 + 6^2 = 64 + 36 = 100 C^2 = 100 C = 10

    Oh, I see what you mean, what I meant was that C in my diagram was 12, not the answer choice C

    anyway, the final answer should be 10 (B)

    sorry for the confusion, I should have picked a different variable name, like x
