it cant be a negative number or zero

so now you are left with 0.5, 2 and 7.9

15.7 - 0.5 = 15.2 ( 15.2/2 = 7.6) this is possible

15.7 - 2 = 13.7 ( 13.7/2 = 6.85) this is possible

15.7 - 7.9 = 7.8 ( 7.8/2 = 3.9) (7.9/2 = 3.95) since the sides would be shorter than half the base this is not possible to form a triangle

so b can be either 0.5 or 2
