Atriangle has two sides of lengths 4 and 15. what value could the length of the third side be? check all that apply.

By the triangle inequality, the sum of lengths of the two shorter sides of a triangle must be greater than the third side.this means that the third side must be less than the sum of the two shorter sides, and the third side must be greater than the (positive) difference of the two remaining sides.put in math terms15-4   < third side < 15+4or11 < third side < 19
