The answer is 0.2867.
tan(30)=.5773502692
60 degrees = ~1.0472 radians
60 degrees = 1.04719755 radians
Rhombus.
tan(-60 degrees) = - sqrt(3)

The exact value of 60 degrees would be 1/2. This is a math problem.
tan(pi/3) = tan (60 degrees) = 1.732 which is square root of 3
Tan(60) = Sin(60)/ Cos(60) Sin(60) = sqrt(3)/2 Cos(60) = 1/2 Hence Sin(60) / Cos(60) = [sqrt(3) / 2] / [1/2} => sqrt(3) / 2 X 2/1 sqrt(3) Hence Tan(60) = sqrt(3) = Numerically = 1.732050808....
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.
Tan 42 degrees = 0.9004
Tan(74 degrees) = 3.487414444.....
tan(11o) = 0.19438 =======
You have a right triangle and can use trig. Degree mode. tan(theta) = adjacent/opposite( y component ) tan( 60 degrees) = (5 m/s)/(y comp.) y component = 5 m/s)/(tan 60 degrees) = 2.887 m/s ( you can call it 3 m/s ) -----------------------------------------------
tan(22.5)=0.414213562
