Question

One of the principal solutions of \( \sqrt{3} \sec x = -2 \) is equal to:

• A. \( \frac{\pi}{4} \)
• B. \( \frac{2\pi}{3} \)
• C. \( \frac{\pi}{6} \)
• D. \( \frac{5\pi}{6} \)

Hint:

To find principal solutions for trigonometric equations, identify the reference angle and determine the quadrants where the function is positive or negative based on the equation.
