The triangle inequality states that the sum of the measures of any two sides of a triangle must be strictly greater than the measure of the third side. Hence if the three sides are a, b, and c, the following relationships must be true.

a + b > c

b + c > a

a + c > b

Let a = 5 and b = 13, then by substitution into the first and third inequalities above then solving for c, you can derive the answers to your two questions.
