Answer
Key
There are two possibilities for 4+ + =18.
18=4+5+9=4+6+8
There are three possibilities to make a sum of 18 with 5 different numbers.
18=1+2+3+4+8=1+2+3+5+7=1+2+4+5+6
In order to use the sets of numbers that do not repeat the sets (4, 6, 8) and (1,
2, 3, 5, 7) must be placed in the triangles of the same color.
Use the same method to find the sum of 21.
