4x - 36 = 2*(x+7) => 4x - 36 = 2x + 14 => 4x - 2x = 50 => x = 25 => DG = 4*25 - 36 = 64.
There are several different angles associated with circles. Perhaps the one that most immediately comes to mind is the central angle. It is the central angle's ability to sweep through an arc of 360 degrees that determines the number of degrees usually thought of as being contained by a circle.
