Answer 2

Answer:

a>5

b<21

Step-by-step explanation:

Two sides of the triangle must be more than the third.When you add 8+13=21 .Thus b is less than 21

The third side is greater than thedifference between two sides.13-8=5 thus a which is the smaller value is more than 5

The range is 5<x<21

Thus a>5 and b<21
