On the other problem, it os 36 percent because o forgot to tell you to subtract it by 100 percent because it is NOT in the shaded
OpenStudy (anonymous):

nope
OpenStudy (plasmataco):
It cannot be 10
OpenStudy (anonymous):
OK
OpenStudy (plasmataco):
The sum of two sides of a triangle has to be bigger than the other side. It can't be equal.

oh ok

oh ok, what do you think? @jim_thompson5910
OpenStudy (plasmataco):
Yes. It is 11 because 11+4 is greater than 14
jimthompson5910 (jim_thompson5910):
let x be the third unknown side
14-4 = 10
14+4 = 18
the third side x must satisfy this inequality 10 < x < 18 for a triangle to be possible
OpenStudy (anonymous):
OK i will go with 11
OpenStudy (plasmataco):
The numbers only go up to 11 so it can only be 11 for it cannot. Be 10 in which it would make a strait line
