we know that 2 sides are 4 and 12, and the sum of any two sides must be greater than the third side so third side + 4 > 12 third side > 8 that leaves us with one answer choice, which one is it?

let x be the third side (some unknown number) x has to be larger than 12-4 = 8 AND x has to be smaller than 12+4 = 16 so x is between 8 and 16 excluding both endpoints algebraically 8 < x < 16 has to be true for a triangle to form
