Question

PLEASE

The three sides of a triangle measure 6, 15, and n. What is the range of possible lengths of n?

6 < n < 15
6 < n < 21
9 < n < 21
9 < n < 15

Answer 1

9 < n < 21

Explanation:

15-6 < n < 15+6

9 < n<21

We are limited by the other two sides of the triangle

It can be no smaller than the other two sides subtracted and no larger than the other two sides added
