I am not sure what "tan A 90 degree" means.
tan(90 degrees) is an expression that is not defined and so cannot be solved.
One way to see why that may be so is to think of tan(x) = sin(x)/cos(x).
When x = 90 degrees,
sin(90) = 1 and cos(90)= 0 that tan(90) = 1/0 and since division by 0 is not defined, tan(90) is not defined.

Tan 90 degree?
It is not defined.
How do you get the center of elbow?
Formula for calculating center to end distance of such elbows is as follows: For 90° Long Radius elbows, center to end dimension given in dimension tables of ASME B16.9 is same as radius of elbow. This is because Tan (90/2) i.e. Tan 45 is 1. Normally custom elbow angles from 45 degree to 90 are cut from 90 degree standard elbow. If that's what you were asking about...
How do you solve for the exact value of tan 2 pi?
tan 2 pi = tan 360º = 0
In Triangle ABC what is the value of Tan A by 2 in terms of its sides if angle B is 90 degrees?
If B is 90 degrees, Tan A is BC / AB. But I don't know what you mean by Tan A by 2.
How do you solve tan a plus tan a for the angle a?
This question doesn't mean anything. Explain more thoroughly.
