Question

A triangle has two sides of length 16.7 and 2.9. What compound inequality describes the possible lengths for the third side, x

Answer 1

13.8 < x < 19.6

Explanation:

the Triangle Sum Inequality states that the sum of any two sides must be equal than the third side

2.9 + x > 16.7

x > 13.8

16.7 + 2.9 > x

19.6 > x

therefore, 13.8 < x < 19.6
