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.

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.

This needs use of trigonometry. A pitch of 7.5/12 = 0.625 This means that the tangent of the angle is 0.625 Using trig tables or calculator, find the angle whose tangent is 0.625 The answer is 32 degrees

Take the inverse tangent -- tan-1(opposite side/adjacent side)

If you know the angle's sine, cosine, or tangent, enter it into the calculator and press <inverse> sine, cosine, or tangent. On MS Calc, in Scientific Mode, using Degrees, enter 0.5, then check Inv and the press sin. You should get 30 degrees. The other functions work similarly.

Use a calculator. There is no simple way to calculate it.

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.

You would have to use its opposite tangent, tan-1on your scientific calculator. It would be tan-1(opposite side/adjacent side), and you must have the opposite and adjacent sides of the angle you are trying to solve.
