Accepted Answer

Step 1: Identify the trigonometric functions or angles given in Column I and understand what each represents. For example, if you have $$ \sec 18^\circ $$, recall that $$ \sec 	heta = \frac{1}{\cos 	heta} . $$Step 2: Calculate or recall the approximate values of the trigonometric functions for the given angles. For instance, compute $$ \sec 18^\circ = \frac{1}{\cos 18^\circ} $$ using a calculator or known cosine values. Step 3: Compare the calculated values with the numerical approximations listed in Column II. Match each function or angle from Column I to the closest numerical value in Column II based on your calculations. Step 4: For angles listed in Column I without explicit functions, consider if they correspond to inverse trigonometric function results or direct angle measures. Use inverse functions like $$ \arcsin, \arccos, \arctan  if $$necessary to find angle approximations. Step 5: Verify each match by checking consistency, such as ensuring that the angle approximations correspond to the correct function values and that the numerical values are within reasonable rounding errors.
