What is 30 degrees of secant?

The secant of an angle in a right triangle is the ratio of the length of the hypotenuse to the length of the adjacent side. For 30 degrees, the secant can be calculated using the cosine function: (\sec(30^\circ) = \frac{1}{\cos(30^\circ)}). Since (\cos(30^\circ) = \frac{\sqrt{3}}{2}), it follows that (\sec(30^\circ) = \frac{2}{\sqrt{3}} \approx 1.155).
