C. 12 cm
as the enlargment is x2, you get that when you do 16/8, and so you multiply 6 x 2 and you get 12, hope this helped!
<u>Given</u>:
The sides of the triangle are 2.8, 2.8 and x
We need to determine the possible sizes for side x.
<u>Values of x:</u>
The possible values of x can be determined using the triangle inequality theorem.
Applying the theorem, we have;
Thus, one of the possible value of x is 0.
Also, applying the same theorem, we have;
Thus, the other value of x is 5.6
Hence, the possible values of x are
The answer is 7.96226 or 8
