please help me and i will love you forever !!!!
thanks for your answers! :) but the choices are

I'm not really sure how to explain this, but I'll do my best.
Take the side of the isosceles that is unequivalent to the other two, and subtract it from 29. Then divide the difference by 2. Make sure the unequal side is always an odd number, otherwise the resulting number will not be evenly divisible.
Hope my algorithm is of use to you, good luck. =)
The perimeter of a triangle is the sum of all 3 sides. If 2 of the sides are the same length (s), then the other side is 29 - 2s
The smallest whole number length of s is 1 inch, (the other side would be 27) and the largest is 14, which makes the other side 1.
So, there are 14 possible side length combinations
