Find the value of x in the image, i got none of these, us that right?

I get A

Step-by-step explanation:

The sides and the division of the base into two parts form a proportion when the line dividing the base line is an angle bisector.

Put in more simple terms

8/(6-2) = (x - 3)/2        Combine

8/4 = (x - 3)/2              Reduce the left

2 = (x - 3) /2                Multiply both sides by 2

2*2 = 2*(x - 3)/2

4 = x - 3                      Add 3 to both sides

4 + 3 = x

x = 7

4
