Webtan θ = 3 2 or tan θ = − 3 4 ∴ sin θ = ± 3 13 and cos θ = ± 2 13 Or, ∴ sin θ = ± 3 5 and cos θ = ∓ 4 5 The given answer is, sin θ = 4 5 and cos θ = 3 5 I thought I needed to discard the negative solution assuming θ is acute. But they haven't indicated a quadrant. Do I assume the quadrant is I only? What am i missing? Thanks again for your help. Websin θ = p / h means perpendicular/hypotenuse cos θ = b / h means base/hypotenuse tan θ = p / b means perpendicular/base This all means, if given two values in a right-angle triangle, we can find another third side of triangle.
