14+13+12+11+10+9+8+7+6+5+4=99 13+12+11+10+9+8+7+6+5=81 14+13+12+11+10+8+7+6=81 Which one is it?
so that leaves 6, 7, 8, 10, 11, 12,and 13. That added up all together is 67 but my teacher said that was incorrect
and the third side can not be 5 or 9

I know it is not 7. So it must be 3, 4, 5, or 6.
I got 2
nvm I got it

I know that triangle ABC and DBC are obtuse and that if the triangle is obtuse then AC^2>AB^2+BC^2
thank you
