Answer

Final Answer: \(\tan^{-1}(-1.3727) \approx \boxed{-53.9270^{\circ}}\)

Steps

Step 1 :The question is asking for the inverse tangent (also known as the arctangent) of -1.3727 in degrees. The inverse tangent function, denoted as \(\tan^{-1}\) or arctan, is the inverse of the tangent function. It returns the angle whose tangent is the input number.

Step 2 :However, this function returns the result in radians, not degrees. To convert radians to degrees, we can use the degrees function.

Step 3 :Calculating the inverse tangent of -1.3727 gives us approximately -0.9412 radians.

Step 4 :Converting -0.9412 radians to degrees gives us approximately -53.927 degrees.

Step 5 :Final Answer: \(\tan^{-1}(-1.3727) \approx \boxed{-53.9270^{\circ}}\)
