Question

A ship is to reach a place 10 degree south of west. in what direction should it be steered if declination at the place is 17 degree west.

Answer 1

The ship is initially at 10 degrees south of west, so to increase the angle at declination of 17 degrees, we have to increase the angle as well. By doing this, we can steer the ship in the direction of the East and then the angle increases to 17 degrees. 

Answer 2

Answer:

Thus, it should be steered west of magnetic north at an angle of $83$°

Explanation:

Concept:

A fixed point on the planet is true north. It differs greatly from magnetic north. When a compass needle aligns with the magnetic field of the Earth, it points in the direction of magnetic north. It's fascinating to note that as the Earth's magnetic field changes through time, so does the magnetic North Pole.

Given:

A ship reached at a place south of west$=10$ degree

The declination of the place$=17$ degree west

To find:

We have to find the direction of the ship.

Solution:

The ship should be guided west of (magnetic) north at an angle of $83$° Since it needs to get to a location $10$° south of west, i.e. along OA.

$=90-17+10$

$=83$°
