knowed that the 3rd side of a triangle need being greater than the difference of the given two sides length and less that the sum of the given two sides length 
so with these knowledge we get 
x > (9-6) so x > 3
and 
x < (9+6) so x < 15

from these result that the 3rd side length can being choice B. 4 ,C. 7,F. 10,
E. 12,

hope this will help you 

The 3rd side length can be chosen B. 4, C. 7, F. 10, E. 12,

We have given that,

A triangle has two sides of lengths 6 and 9.

knew that the 3rd side of a triangle needs to be greater than the difference between the given two sides' length and less that the sum of the given two sides' length.

What is the triangle?

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \(\triangle\) ABC.

So with this knowledge, we get

x > (9-6) so x > 3

and

x < (9+6) so x < 15

From these results, the 3rd side length can be choice B. 4, C. 7, F. 10,

E. 12,
