# Thread: WORD PROBLEM! Bearings and stuff....AHH!

1. ## WORD PROBLEM! Bearings and stuff....AHH!

Captain Black is on a fishing boat that leaves its pier and heads east. After traveling for 30 miles, there is a report warning of rough seas directly south. Captain Black turns the boat and follows a bearing of S45D.W [South 45 Degrees West] for 12 miles.

Question:
1.At this time, how far is Captain Black from the boat's pier?
2.What bearing could the boat have orginally taken to arrive at this spot?

As always with these problems first draw a picture.

See the attached picture, you need to find the angle a amd the distance x.

It looks to me as though you need the cosine rule to find x, then the
sine rule to find a.

3. CaptainBlack what do you use to generate images?

Power point, and/or whatever the equivalent tool supplied with open
office is called.

It's easy if you do this sort of thing all the time.

After producing the diagram in power point I display it as large as possible
and use [alt][prnt scn] to capture the drawing as a bit map to the
clip board. This is then pasted as a new image into a photo editor and
then cropped and saved at a suitable size as a jpg or png file (png is
preferable as it uses lossless compression - but the file size is not as small as
a jpg).
