Answer:
AC=16 inches
Step-by-step explanation:
Given two side lengths of a triangle as x and y (x greater than y), the third side z must satisfy the inequality:
x - y ≤ z ≤ x + y
The side lengths are x=17 and y=10, thus:
17 - 10 ≤ z ≤ 17 + 10
7 ≤ z ≤ 27
The third side must be between 7 and 27 inches. The only choice that satisfies the conditions is AC=16 inches
