"A scale factor is a number which scales, or multiplies, some quantity. ... In the field of measurements, the scale factor of an instrument is sometimes referred to as sensitivity. The ratio of any two corresponding lengths in two similar geometric figures is also called a scale factor." (not my wording but i hope this helps)
Answer:

Step-by-step explanation:
The cotangent of theta is:

For pi/2 < theta< pi
This means that the angle is in the second quadrant. In the second quadrant, the cosine is negative and the sine is positive. This means that the cotangent will be negative.
Secant:

In this question

So

Using cross multiplication



Now we apply the following trigonometric identity:






Since the angle is in the second quadrant, the sine is positive.

Finally, the cotangent:
