Answer:
I believe the answer is C. Please let me know if I am wrong
Step-by-step explanation:
Answer: Step 2
Step-by-step explanation:
The scale factor is defined as image/preimage, so since the image is circle F and the preimage is circle E, k should be equal to (radius of F)/(radius of E), or 1/2, not 2.
Answer:
the reference angle is given by 
sine = negative
cosine = positive
tangent = negative
Step-by-step explanation:
We have been given the angle 
The angle lies in Quadrant IV. Hence, in order to find the reference angle, we can subtract this angle with 
Therefore, the reference angle is given by

In Quadrant IV, cosine and secant functions are positive and rest trigonometric functions are negative.
Thus, we have
sine = negative
cosine = positive
tangent = negative
