Question

A triangle has the side lengths of 7.5 and 4.8, what is the range of lengths for the third side

Answer 1

2.7 < x 12.3

Explanation:

using triangle inequality theorem:

(3 scenarios, discount the one that produce a negative)

4.8 + 7.5 > x x < 12.3

4.8 + x > 7.5 x > 2.7

7.5 + x > 4.8 (discount)
