There is no simple way. You could use published tables but I don't suppose that is what you meant.
Usually there is an inverse key or( tan -1 )key for this
since x is negative you use the identity cot-1(x)=tan-1(1/x)+pi. Tan-1(1/-sqrt3) + pi 5pi/6 + pi =pi
You cannot because you do not know what R is.
that queation doesnt make any sence u retard because u cant get the tan of a triangle u can only get the tan of a number To find the tan of an angle you want to use this ratio: Opposite side divided by adjacent side Once you find the answer, on a scientific calculator you enter in your answer and hit the inv button then the tan button and it should give you your answer.
The angle in a rise of 2 feet in 4.5 feet can be found using trigonometry. Using the tangent function (tan), we can take the inverse tangent (arctan) of the rise over the run. In this case, arctan(2/4.5) is approximately 25.20 degrees.

It is a trigonometric equation for a right triangle, to find a non-right-angle angle. Using SOHCAHTOA, it is the opposite side divided by the adjacent angle
Usually there is an inverse key or( tan -1 )key for this
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.
tan A says nothing about tan B without further information.
since x is negative you use the identity cot-1(x)=tan-1(1/x)+pi. Tan-1(1/-sqrt3) + pi 5pi/6 + pi =pi
To get this answer, type in tan(28) in your calculator. It should come out to be about .532. Make sure your calculator is in Degree mode.
The value of tan A is not clear from the question.However, sin A = sqrt[tan^2 A /(tan^2 A + 1)]
It actually does something to the number
You cannot because you do not know what R is.
