The number of the product is 9
No association would be the answer.
Since the total measure of all the angles of a triangle is always 180, solve for x with the equation: 3x+1+2x-3+9x=180. x=13. Now plug in x and look for the smallest one, which will be B. 23 degrees.
Check the picture below.

since the distance AB cannot be a negative value, thus is not -3-√(130).
