Does cos 60° mean that the side adjacent to the 60° angle measures 1 unit and the hypotenuse measures 2 units? Explain.?

    cos60° = 1/2 => adjacent/hypotenuse

    This means the length of the adjacent side compared to the length of the hypotenuse is in the ratio 1 : 2

    We could have a situation where we have,

    adjacent = 2.8 and hypotenuse = 5.6

    so, cosθ = 2.8/5.6 => 1/2

    i.e.  θ = 60°

    Yes and no. The cosine is directly derived from the unit circle, so the real truth is that the side adjacent to the 60° angle measures 0.5 and the hypotenuse measures 1.0 units. (By definition, the radius of the unit circle is 1.0).

    P.S. Cosine (60°)=0.5, not 1.0.

    Yes, cos 60° means that the side adjacent to the 60° angle measures 1 unit and the hypotenuse measures 2 units.
