Answer:

  • cos(θ) = -1/2
  • tan(θ) = √3

Step-by-step explanation:

You know that ...

  • cos(θ)² = 1 - sin(θ)²
  • tan(θ) = sin(θ)/cos(θ)
  • cosine is negative in the third quadrant (where π < θ < 3π/2)

Using what you know about the relationships of these trig functions, you can find ...

  cos(θ)² = 1 - ((-√3)/2)² = 1 - 3/4 = 1/4

  cos(θ) = -1/2 . . . . . negative square root of 1/4

__

  tan(θ) = sin(θ)/cos(θ) = ((-√3)/2)/(-1/2)

  tan(θ) = √3
