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 the range is 14>x>4

I know it is not 7. So it must be 3, 4, 5, or 6.
I got 2
nvm I got it
I plugged the numbers in and I got that the least possible integral number for triangle ABC is 11 but the least possible integral number for triangle DBC is 19 and that base is too large for triangle ABC.
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
