Ответ:
The bearing is the angle measured relative to or from the Northern
direction.
The ship's distance East from its starting point is approximately 10.26 km.
Reasons:
The given bearing of the ship's path, θ = 020°
The distance the ship has travelled = 30 km.
Required:
The ship's distance East from its starting position
Solution:
By using trigonometric ratios, we have;
Which gives;
![sin(20^{\circ}) = \dfrac{Ship's \ distance \ East \ from \ its \ starting \ point}{30 \ km}](/tpl/images/0909/9647/ac3f6.png)
The ship's distance East from its starting point = 30 km × sin(20°) ≈ 10.26 km.Learn more here:

Ответ:
The ship travels approximately 10.261 meters to the East.
Step-by-step explanation:
At first we introduce a graphical description of the statement as an attachment below. Let suppose that bearing is respect to the North-direction, then the change in position in the East direction is modelled by the following Trigonometric formula:
Where:
If we know that
and
, then the distance in the East direction is:
The ship travels approximately 10.261 meters to the East.
