Scale factor is a ratio. The correct option is C.
<h3>How are
scale drawings formed?</h3>
For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.
Then it means

All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.
The length of AB can be written as,
AB = √[(1-4)²+ (1-1)²]
AB = 3
Since the length A'B' is 6 units, therefore, the scale factor will be,
Scale factor = (Length after transformation)/(Length before transformation)
Scale factor = 6 /3 = 2
Hence, the correct option is C.

Answer:
74 degrees
Step-by-step explanation:
The arc degree measurement of the arc that is colored in orange is given as 254 degrees.
The remaining part is the part in green.
The green part plus the orange part should equal 360 degrees because that would make a full rotation around the circle.
.
The green arc has measurement 106 degrees.
We can find x by computing half the difference of the arcs there.
That is,
