Answer 2

Answer:

Step-by-step explanation:

to solve this question, we have to know the angle inequality property:

the sum of any 2 sides of a triangle is always greater than the third side.

so, we can name the sides of the triangle and they are as follows: a, b and c

now, to find the third side, we apply this property. we need to find c

a+b > c

4+8>c

12>c, so the biggest length of c possible is 11, since 11 is the number just smaller than 12.
