A ship sails on a bearing of 020° for 30 km.
zepelin [54]

Answer:

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:

x = r\cdot \sin \theta (1)

Where:

r - Distance travelled by the ship, measured in kilometers.

\theta - Bearing angle, measured in sexagesimal degrees.

x - Distance component in the east direction, measured in kilometers.

If we know that r = 30\,km and \theta = 20^{\circ}, then the distance in the East direction is:

x = (30\,km)\cdot \sin 20^{\circ}

x \approx 10.261\,m

The ship travels approximately 10.261 meters to the East.

What is s?? <br> A 44° <br> B 35.3° <br> C. 37.9°<br> D. 22°
melisa1 [442]

Answer: Choice B) 35.3 degrees

======================================================

Work Shown:

Apply the law of sines

sin(S)/s = sin(R)/r

sin(S)/16 = sin(120)/24

sin(S) = 16*sin(120)/24

sin(S) = 0.57735026918962

S = arcsin(0.57735026918962)

S = 35.2643896827542

S = 35.3

Make sure your calculator is in degree mode.
