Question

Which are possible lengths of the sides for a triangle?

A. 4, 2, 6
B. 4, 3,9
C. 3, 4,7
D. 9, 7, 11

Answer 1

D

Explanation:

im not sure if they can be the same length, but heres the explanation: so a+b is higher than c, (9=a, 7=b, 11=c) but c is the bigger number by itself. so since a+b is higher added together, it makes it a triangle. sorry if this is wrong but i think its right.
