Answer:
c = -5
d = -10
Step-by-step explanation:
A biologist is tracking a bird when it was at A.
Coordinates of point A are (2, 4).
This bird moves from point A to point B.
Coordinates of the point B are (-3, -6).
Vector form of vector represented by 
By substituting the coordinates of points A and B,

= < -5, -10 >

By comparing it with the vector form of [cd]
c = -5
d = -10

Answer: 35.9 degrees
Step-by-step explanation:
Since cosine(x) is adjacent/hypotenuse, cosine(x) = 47/58.
Therefore we can take the arc cosine of 47/58, and we get x is about 35.9
