Question

If the lengths of two sides of a triangle are 5 and 9, which could be the length of the third side? A. 2 B. 4 C. 7 D. 14

Answer 1

C

Explanation:

Given 2 sides then the third side x is in the interval

difference of 2 sides < x < sum of 2 sides, that is

9 - 5 < x < 9 + 5

4 < x < 14

Thus the third side could be 7 → C
