Answer:
1 and 9
Step-by-step explanation:
By the Triangle Inequality Theorem, the sum of two side lengths of a triangle is always greater than the length of the third side.
In other words, in a triangle with side lengths and
we always have
Applying this to this question, the other side length, must satisfy the following inequalities:
Solving these inequalities gives
Combining these solutions, we have Therefore, the length of the third side falls between 1 and 9.
