The two longer sides of a triangle measure 16 and 22 which of the following is a possible length of the shortest side

The rule for sides of a triangle is that it has to be less than the sum of the other two sides, and more than the difference of the two sides. So, 16 + 22 = 38, which means that it has to be less than 38, and 22 - 16 = 6, which means it has to be more than 6. I don't know the options you're given, but less than 38 and more than 6 are your boundaries. I hope this helps!

No because if you do the higher number minus the lower number you will get a positive. if you do it the other way around you will get a negative number
