Answer:
yes
Step-by-step explanation:
For the given sides to form a triangle.
The sum of any 2 sides must be greater than the third side.
12.2 + 6.8 = 19 > 6.5
12.2 + 6.5 = 18.7 > 6.8
6.8 + 6.5 = 13.3 > 12.2
Thus the 3 given sides form a triangle
number one and four
x = 5
5 + 4 = 4 + 5
9 = 9
That means this statement is true.
