Recall that the sum of the exterior angles of any polygon is always \(360^\circ\).
Since the polygon is a regular decagon, it has 10 equal exterior angles.
Let each exterior angle be given by the expression \$3x + 6$ degrees.
Set up the equation for the sum of all exterior angles: \(10 \times (3x + 6) = 360\).
Solve the equation for \(x\) by first expanding and then isolating \(x\).
