You cannot.
Usually there is an inverse key or( tan -1 )key for this
To find the tangent of 1, you can use the inverse tangent function (arctan) on a calculator. Simply input 1 into the arctan function and calculate the result. The tangent of 1 is approximately 0.7854.
To find the angle ( a ) for which ( \tan a = 0.42 ), you can use the inverse tangent function (also known as arctangent). This can be calculated using a calculator or software that provides trigonometric functions. The result will give you ( a ) in radians or degrees, depending on your calculator's settings. Specifically, ( a \approx 22.62^\circ ) or ( a \approx 0.394 ) radians.
Given only the measure of an angle, use a scientific calculator or a book of mathematical tables (if you can find one!). There are infinite series but they are not particularly easy to work with.
Nowadays you cannot do it without a calculator.

Well, isn't that a happy little question! The inverse tangent of 0.3125 is approximately 17.5 degrees. Just imagine that angle gently resting in a meadow of mathematical serenity, bringing balance and harmony to your calculations. Remember, there are no mistakes in math, just happy little numbers waiting to be discovered.

Take the inverse tangent -- tan-1(opposite side/adjacent side)
Use a calculator. There is no simple way to calculate it.
The calculator won't do it.On the calculator, the button marked 10x gives youthe inverse log of the number in the window.
First make sure your calculator is in 'Degree Mode (D)'. Then using the 'Inverse' of 'Sin' , shown as 'ArcSin' or ' Sin^(-1)' . enter '0.5', followed by '=' . The answer should be '30' ( 30 degrees).
to find the measure of an angle. EX: if sin A = 0.1234, then inv sin (0.1234) will give you the measure of angle A

The inverse of a logarithmic function is an exponential function. So to find the "inverse" of the log function, you use the universal power key, unless you're finding the inverse of a natural log, then you use the e^x key.
