sine
1+ square root of 5 over 2 not positive
tangent
The ratio is [ 4/x per unit ].
It is a pure number and numbers do not have units. If you are thinking of pi in the context of a circle, it is the ratio of the length of the circumference to the length of the diameter. Length/Length, so there are no units.
It's called the "scale."
# is the ratio of the demensions in the drawing to the corresponding actual dimensions. The scale factor for a scale drawing is the ratio of the dimensions in the drawing to the corresponding acual bimensions.
It is (or should be) given by the key.
The scale.
The scale indicates how many units of length of the actual object are represented by each unit of length in the drawing.
The scale factor of a scale drawing is the ratio of any length in the drawing to the true corresponding length in the "real" object.

24.75 ft.
It would be: 96/12 = 8 inches
The scale written in the right side of the drawing shows the true length. Any drawing has perspective, but to determine the length of the specifications, one must have the actual scale by the designer. This is always defined by the draftsman and noted somewhere either on the right upper side corner or the lower right side corner.
