The reference angle of something is its angle measure in the first quadrant. angle is in the fourth quadrant 2 pi - 3pi/6 3pi/2 radians and that is your reference angle. hope this helps
x = 11π / 6 = 330 ° To find the reference angle for angle in Quadrant IV the formula is: α = 360° - x α = 360° - 330° = 30° Answer: The referenceangle is 30° or π/6.
