Answer:
The distance of ship B from the Harbor is 32.26 miles
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Equations.
I have added a visual aid of the problem. As we can see the courses of both ship to the harbor forms a triangle with ship B being the hypotenuse. Since we are given the distance of the course for ship A and the angle between both ships, we can use this information with the <u>COSINE operator</u> to solve for the length of the course of ship B.

.... flip both fractions.
.... multiply both sides by 22


So the distance of ship B from the Harbor is 32.26 miles

Answer:
D
Step-by-step explanation:
square the 16 and 4.2 and sun them up due to the pythagorean theorem (a^2+b^2=c^2)
get 273.64 and take the sqrt of that to find c.
get 16.54 and round to 17 :)
There's many guides on google on how to do that.
