Answer:
15 < X > 31
Step-by-step explanation:
From triangle theorem,a triangle with sides X, Y, Z, the sum of any 2 sides must be greater than the third side i.e;
1. X + Y > Z
2. Y + Z > X
3. X + Z > Y
We are given 2 sides say Y = 8 and Z = 23.
Thus,Range of values is expressed as;
Z - Y < X > Z + Y
23 - 8 < X > 23 + 8
15 < X > 31
