a scale
sine
1+ square root of 5 over 2 not positive
tangent
The ratio is [ 4/x per unit ].
sin θ : 1 = the length of opposite side to angle θ : the length of the hypotenuse
It's called the "scale."
To determine the length of the object in the drawing, use the scale of 3 inches for every 4 feet. First, find the ratio of the actual length to the scale length: ( 24 \text{ ft} \div 4 \text{ ft} = 6 ). Then, multiply this ratio by the scale length: ( 6 \times 3 \text{ in} = 18 \text{ in} ). Therefore, the length of the object in the drawing is 18 inches.
# 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.
Scale
To find the actual measurement in a scale drawing, first identify the scale used in the drawing (e.g., 1:100 means 1 unit on the drawing equals 100 units in reality). Measure the length of the object in the drawing using a ruler. Then, multiply that measurement by the scale factor to convert it to the actual size. For example, if the length measured is 2 cm on a 1:100 scale, the actual length would be 2 cm × 100 = 200 cm.

To find the scale factor of the drawing, first convert the actual length from feet to inches since the drawing's length is in inches. There are 12 inches in a foot, so 8 feet equals 96 inches. The scale factor can then be calculated by dividing the drawing length (4 inches) by the actual length (96 inches), resulting in a scale factor of 1:24. This means that 1 inch on the drawing represents 24 inches in reality.
To find the actual length using a scale ratio, first identify the scale ratio provided (e.g., 1:100). This means that 1 unit on the scale represents 100 units in reality. Measure the length on the scale and then multiply it by the scale factor. For example, if the measured length is 2 cm on the scale, the actual length would be 2 cm × 100 = 200 cm.
