120, 300 degrees (for angles between 0 and 360 degrees).
In radians this is 2π/3, 5π/3 radians.
Step-by-step explanation:
Arctan ( - sq rt 3) is the angles (in radians or degrees) for which the tangent is - sq rt 3.
Arctan sq rt 3 = 60 degrees or π/3 radians.
As the tangent is negative in the 2nd and 4th quadrants arctan (-sq rt 3) = 120, 300 degrees.
