We have the following:

solving for x

The solution of x is equal to 28, therefore 12 is not a solution of the equation
Hello!
To solve this we use the equation sin60 = (s/2) / (d/2)
s is a side of the triangle
d is the diameter
sin60 = s/d




put 6 in for s


d = 6.9
The answer is C) 6.9
Hope this helps!
