restriction on x for a triangle

Question

In triangle ABC, the measure of angle A is greater than the measure of angle C. Side AB is 4x+48 and side BC is 8-x. what is the restrictions on x?

Answer 1

Side BC is opposite angle A

Side AB is opposite angle C

The side opposite the smaller angle is always smaller

Since angle C is smaller, Side AB < Side BC:

4x + 48 < 8 - x

5x < -40

x < -5
