Answer 1

9514 1404 393

Answer:

C: 11.5 cm, 4.2 cm, 7.6 cm

Explanation:

In order for the lengths to form a triangle, the sum of the shortest two must exceed the longest.

A. 5.4 +5.4 = 10.8 < 12.6

B. 1.3 +5.9 = 7.2

C. 4.2 +7.6 = 11.8 > 11.5 . . . . will make a triangle

D. 3.1 +6.6 = 9.7 < 10.4
