10/6 = 1 2/3
This is because 5 + 5 =10/6
Divide 19 by six.
This gives you 1 2/3
(5,12,13) is a right triangle and can be constructed.
All the others do not satisfy the triangle inequality, i.e. the sum of two short sides must exceed the long side in order for the triangle to be constructed.
Examples:
2+11<15, so no
3+7<11, so no
4+8<15, so no
but 5+12>13 so yes, it can be constructed.
What is the total cost or it is unsolvable?
I think the answer is: 6 = -21
