We’ll go for LOGICAL because there is a simple logic behind the question.
All the angles together make up a circle, which equals 360 degrees: \(24x = 360\). Since we are looking for 120 degrees, we can divide the equation by 3 and arrive at \(8x = 120\). There aren’t any adjacent angles that can be added to up to create 8, except the angle \(8x\) itself. So the largest number of adjacent angles is 1.

Isn't that the smallest number of adjacent angles? Largest number should be 3 (x + 2x + 3x).
