Question

Two sides of a triangle are 15 and 8. Which of the following cannot be the third side? 09 13 21 25l​

Answer 1

9

Explanation:

The third side cannot be 9 because one of the triangle side lengths must be greater than the other two combined. In this case, 9 + 8 = 17. Since 15 is smaller than 17, 9 cannot be the length of the other side.
