OpenStudy (poopsiedoodle):

Hey poopsiedoodle you gave me two medals, but I couldn't send you a message to thank you, so thank you:)

OpenStudy (poopsiedoodle):

@MChromer, yw @redpanda123 is the "10" the length of the side that cuts it in half?

OpenStudy (anonymous):

its the hypotnuse

OpenStudy (poopsiedoodle):

K. In that case, do you know about the rule for side lengths in triangles?

OpenStudy (anonymous):

yes

OpenStudy (poopsiedoodle):

K. So, since two sides, when added together, always have to have a bigger combined length than the third side, we can go ahead and rule out everything from 3 and under.

OpenStudy (poopsiedoodle):

So, 3 < a.

OpenStudy (anonymous):

and then ?

OpenStudy (poopsiedoodle):

Does it have to be an inequality, or an exact number?

OpenStudy (poopsiedoodle):

Because I'm pretty sure it can be anywhere from 4 to 9. Anyway, if it's an inequality, it's 3<a<10

OpenStudy (anonymous):

the choices are

OpenStudy (poopsiedoodle):

Oops. Just now noticed that. Let me do the math here. Sec.

OpenStudy (poopsiedoodle):

I'm thinking it's B. It can actually be anywhere from 3.000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000(and lots more zeroes)1 and 9.99999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999(you get the picture )

OpenStudy (poopsiedoodle):

actually, wait, nevermind. It would have to be at least 3.34. It's not B.
