Answer:
Step-by-step explanation:
Sinθ =
If, sinθ = - and π < θ <
Since, sinθ is negative, angle θ will be in IIIrd quadrant.
And the measure of angle θ will be (180° + 30°)
θ = 210°
It's necessary to remember that tangent and cotangent of angle θ in quadrant III are positive.
Therefore, cos(210°) =
tan(210°) =
csc(210°) =
sec(210°) =
cot(210°) = √3
