Chang knows one side of a triangle is 13 cm. which set of two sides is possible for the lengths of the other two sides of this triangle?

5 cm and 8 cm
6 cm and 7 cm
7 cm and 2 cm
8 cm and 8 cm

The other 2 sides added have to be greater than 13

Option A: 5 + 8 = 13. 13 is not greater than 13 so it's not the answer.

B: 6 + 7 = 13. Same thing as option A

C: 7 + 2 = 9. 9 is less than 13 so not the answer.

D: 8 + 8 = 16. 16 is greater than 13 so D is the correct answer.
