Verified step by step guidance

Understand that the problem is asking for the evaluation of the inverse tangent function, $ \tan^{-1}(5) $, which gives the angle whose tangent is 5.

Recognize that the result of $ \tan^{-1}(5) $ will be an angle expressed in radians.

Use a calculator to find $ \tan^{-1}(5) $. Ensure your calculator is set to radian mode to get the correct unit.

Once you have the result from the calculator, round the value to two decimal places as specified in the problem.

Verify the rounded result to ensure it matches the expected format and check if it aligns with the given correct answer.
