The answer is 0.2867.
tan(30)=.5773502692
1.732
tan-1(0.6009) =31.0016578 degrees
10 x tan(51) = 12.349 (rounded) tan(510) = negative 0.5774 (rounded)
When the angle of elevation equals 45 degrees. tan-1(1) = 45 degrees.
The cotangent function is the reciprocal of the tangent function, so cot(115 degrees) is equivalent to 1/tan(115 degrees). Since tan(115 degrees) is equivalent to -tan(65 degrees) due to the periodicity of the tangent function, cot(115 degrees) simplifies to -tan(65 degrees), which corresponds to option A.
cot 115 deg = - tan25 deg
The angle 300 degrees is in the fourth quadrant of the unit circle, where the tangent function is negative. Therefore, the sign of tan 300 degrees is negative. Specifically, tan 300 degrees can be calculated as tan(360 degrees - 60 degrees), which equals -tan(60 degrees), giving a negative value. Thus, tan 300 degrees is negative.
Tan 42 degrees = 0.9004
Tan(74 degrees) = 3.487414444.....
tan(11o) = 0.19438 =======
tan(22.5)=0.414213562
it is tan 89.343 degrees
x = tan-1(5) = 78.69 degrees
ArcTan is another name for ;Inverse Tan' or 'Tan^*-1) Hence ArcTan(0.55431) = 29.00004157 degrees. Effectively 29 degrees.
Tan(5.2 degrees) = 0.0910 Tan(5.2 radians) = -1.8856
tan(61°) = 1.80405 (rounded)
