A ship travels 84 km on a bearing of 17°, and then travels on a bearing of 107° for 135 km. Find the distance of the end of the trip from the starting point, to the nearest kilometer. (1 point)

159 km

Explanation:

In order to find the distance from starting point to ending point, we have to find the net displacement.

To do that, we have to resolve each displacement along the x- and y- direction.

Here the displacements are:

1) 84 km on a bearing of 17°

2) 135 km on a bearing of 107°

Keeping in mind that the bearing is measured as clockwise from north, we resolve each displacement as follows:

1)

2)

Therefore, the components of the net  displacement are

So, the distance  from starting to ending point is the magnitude of the net displacement:

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
