None of the other answers are correct
25
6

A: 35

Step-by-step explanation:

DG is the combined segments DO and OG. In other words:

We know that DG is 60. DO is (4x-3) and OG is (2x+21). So, substitute:

Solve for x. Combine like terms:

Subtract 18 from both sides:

Divide both sides by 6. Hence, the value of x is:

GO is defined as (2x+21).

So, to find GO, we can now substitute 7 for x and evaluate. Therefore:

Hence, our answer is A.
