For example if I have tan30 and I type it in the calculator to get 0,577350269 is there a way to revert that number with the calculator to get 30 degrees? Another example of the same type if I wanna get tanß = cosα / (2 - sinα) and the α = 30 degrees, so it is = 0,577350269 is there a way to revert it with the calculator to degrees so the ß would be 30 degrees insted of 0,577350269?

Depending on your calculator, yes! Most calculators that have the sin, cos, tan functions also come with sin^(-1), cos^(-1) and tan^(-1) functions!
If tan(30)=0.577, then tan^(-1)(0.577)=30 (if you want this result in DEGREES instead of RADIANS, make sure you change the settings on your calculator (it's different for every calculator).
