tan(9) + tan(81) - tan(27) - tan(63) = 4
cot 115 deg = - tan25 deg
tan (30 degrees) would be equal to 0.577350269.

If B is 90 degrees, Tan A is BC / AB. But I don't know what you mean by Tan A by 2.

B: -tan(25)
tan(9) + tan(81) - tan(27) - tan(63) = 4
cot 115 deg = - tan25 deg
Tan 42 degrees = 0.9004
tan(11o) = 0.19438 =======
tan(22.5)=0.414213562
The answer is 0.2867.
it is tan 89.343 degrees
4
x = tan-1(5) = 78.69 degrees
Tan(5.2 degrees) = 0.0910 Tan(5.2 radians) = -1.8856
