Final answer:
To write an inequality describing the range of x for a pair of triangles, consider the lengths of their sides or their angle measures.
Step-by-step explanation:
To write an inequality describing the range of x for a pair of triangles, you need to consider the lengths of their sides or their angle measures. Let's say we have two triangles, Triangle A and Triangle B.
If you are given the lengths of the sides of the triangles, you can use inequalities to compare them. For example, if Triangle A has side lengths a, b, and c, and Triangle B has side lengths x, y, and z, you can write the inequality a < x < c to represent the range of x that is valid for both triangles.
If you are given the angle measures of the triangles, you can use inequalities to compare them as well. For example, if Triangle A has angles A, B, and C, and Triangle B has angles X, Y, and Z, you can write the inequality B < Y < C to represent the range of Y that is valid for both triangles.
