  17. What trig function to use when a triangle with a missing side opposite of θ
    Cosine θ = Adjacent / Hypotenuse
  18. What trig function to use when a triangle with a missing side adjacent of θ
    Sine θ = Adjacent / Hypotenuse
  19. What trig function to use when a triangle with a missing side Hypotenuse of θ
    Tangent θ = Opposite / Adjacent
  20. to find θ knowing Opposite and Hypotenuse
    Sin-1(Opposite/Hypotenuse) = θ
  21. to find θ knowing Adjacent and Hypotenuse
    Cos-1(Adjacent/Hypotenuse) = θ
  22. to find θ knowing Opposite and Adjacent
    Tan-1(Opposite/Adjacent) = θ
