Answer:
0 < x < 14
Step-by-step explanation:
We are given an isosceles triangle. This means that it has two congruent sides, or 2 sides that are the same length.
To find the possible range of values for the non-congruent side, we can make an inequality.
First, we know that it CAN'T be less than or equal to 0. If it's zero, then the triangle is a line. In inequality form, this is:
x > 0 or 0 < x
Next, we know that it CAN'T be greater than or equal to the sum of the congruent side lengths. Again, the triangle would just be a line otherwise. In inequality form, this is:
x < 7 + 7
x < 14
Putting these two inequalities together, we get:
0 < x < 14
