Answer:
13<X<17
Step-by-step explanation:
Triangular Inequalities state that a side is always greater than the absolute value of the difference of the other two sides and less than the sum of the other two sides. You use the inequality |a-b|<c<a+b with a, b, and c as the lengths of the sides.
When you plug in the numbers, (X being c, 2 being b, and 15 being a) you get
|15-2|<X<15+2
|13|<X<17
Which brings us to our final answer of:
13<X<17
