How to do true bearings?

Question

Please give instructions on how to answer this question, because I don't understand true bearings at all... :) Thanks!

A speedboat travels 26 km on a true bearing of 065°. Find how far the boat is to the east of its starting point. Round off to two decimal places.

Answer 1

True bearing is a navigational angle; to be distinguished from a mathematical angle.



True bearing is distinguished from the other navigational angle, relative bearing. Relative bearing is measured relative to the bow of the ship. True bearing is measured relative to due north.



So imagine a compass.

True bearing = 0 : north

True bearing = 90: east

True bearing = 180: south

True bearing = 270: west



Notice that true bearing is measured clockwise from north.

A mathematical angle is measured counter-clockwise from east.



In particular, Mathematical angle = A =

A = 90 - true bearing + 360n; where n is an integer which brings the value of A into the range 0 <= A <= 360.

===



so a true bearing of 065 corresponds to A = 25 deg.

So the boat would be R_east = 26km cos(25 deg)

Answer 2

True Bearings

Answer 3

imagine a clock

true bearings start from the number 3 and go backwards

so 090 is at 12 and 180 is at 9

030 would be at 2

065 would be inbetween 12 and 1 but closer to 1

you will need a protractor to do this

Why are all the answers so short these days?
