Answers

8 cm and 9 cm

Explanation:

To estimate the sides of triangle we must understand that any side of a triangle is greater than the differences between any two sides and also less than the sum of the two sides.

In this problem;

One of the sides is 13cm;

According to our theorem, this sides is less than the sum of the other two sides and greater than difference between the two sides.

8 cm and 9 cm is the correct choice;

if the other two sides are 8cm and 9cm;

9cm - 8cm = 1cm

9cm + 8cm = 17cm

13cm is in between them.
