Answer:
B
Step-by-step explanation:
The distance d from port c to port a from the given ship movement is gotten as; 7.7 miles.
<h3>How to calculate bearing distance? </h3>
We are given;
Ferry travels east 3.5 miles from Port b.
Then it turns 75° south and travels for 6 miles till it gets to Port c
To get the distance d from port c to port a, we would make use of cosine rule which is;
c = √(a² + b² - 2ab*cos C)
Thus;
d = √(3.5² + 6² - 2(3.5 * 6)*cos 75))
d = 7.7 miles
