Okay, I am stuck in this geometry question that actually seems pretty simple. Am I using the wrong method?

See, I tried to find the value for x, and got 7.2, but apparently, that is incorrect. Am I using the wrong method to solve this?

anonymous · Answer

i can see why you are stuck
it is not clear from that picture which side is largest

anonymous · Answer

maybe try $$\frac{x}{6}=\frac{24}{20}$$

anonymous · Answer

i get $$x=\frac{36}{5}$$ but that is just my guess

anonymous · Answer

oh, that is $7.2$ and you said it was wrong, damn

darryqx · Answer

Yes, I see. I would assume it's segment BC, but it doesn't really state it. And yes, I did that equation and it came out to the same answer. I'm not sure why it would be incorrect, but it is.

anonymous · Answer

only other guess i would have is $$\frac{x}{6}=\frac{20}{24}$$

anonymous · Answer

in that case you get $x=5$ 
it has to be one of those two for sure!

anonymous · Answer

OOH i see !

anonymous · Answer

it says ABC and DEF in that order, so yes, the second one

darryqx · Answer

Ah, I see. Thank you so much, I really do appreciate it.
