B: -tan(25)
Tan 42 degrees = 0.9004
tan(11o) = 0.19438 =======
tan(22.5)=0.414213562
tan(-60 degrees) = - sqrt(3)
tan(10 deg) = 0.1763, approx.
10 x tan(51) = 12.349 (rounded) tan(510) = negative 0.5774 (rounded)
B: -tan(25)
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
x = tan-1(5) = 78.69 degrees
Tan(5.2 degrees) = 0.0910 Tan(5.2 radians) = -1.8856
