zepdrix (zepdrix):

|dw:1439006866593:dw|Hmm ok cool we found another :O

zepdrix (zepdrix):

Can you see any other location? :) I think I see one more!!

OpenStudy (anonymous):

zepdrix (zepdrix):

|dw:1439006923678:dw|There are a bunch of places that clearly WON'T work, ya?

zepdrix (zepdrix):

But I see oneeeee :O

OpenStudy (anonymous):

I'm so confused :o cause my options are 0, 1, 2, 3

zepdrix (zepdrix):

ya we found 2 so far. and im saying that i think i see a third option, without giving it away just yet lol <.<

zepdrix (zepdrix):

my last picture was showing options that will not work

OpenStudy (anonymous):

Oh! haha I thought the answer was 4, I was like .. :o

zepdrix (zepdrix):

OpenStudy (anonymous):

NO WAY

zepdrix (zepdrix):

"touches" both circles like we need a tangent line to do, and its common for both, ya? :O

zepdrix (zepdrix):

ahh i stole all the fun on that one :P oh well, i guess that gives us our answer, ya? :D since clearly our options don't give us anything more than 3.

OpenStudy (anonymous):
