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?
3
5 cm and 8 cm
O 6 cm and 7 cm
0 7 cm and 2 cm
O 8 cm and 9 cm
In order to find out, you add both 8 and 9 together. If the sum is above/higher than the number 13, they can all be made into a triangle. 8+9 is 17 and 17 is higher than 13.
