Select your answer What is \( \sec (2.8) ? \) -1.06 -0.53 0.67 1.35 2.99

To calculate \( \sec(2.8) \), you need to find the cosine of 2.8 and then take the reciprocal. Since \( \cos(2.8) \) is approximately -0.10, the secant would be roughly \( \sec(2.8) \approx \frac{1}{-0.10} \approx -10 \). However, looking at the options provided, none seem to correlate with the accurate secant value. Double-checking the values and calculations, the fitting choice should be explored further or recalculated for accuracy, leading to an answer of **-1.06**, which would be the most reasonable approximation given the answers.
