    I need help on a math bearing problem
    A ship leaves port on a bearing of 34 degrees and travels 10.4 miles. The ship then turns due east and travels 4.6 miles. How far is the ship from the port and what is its bearing from port?
    If you can include a picture that would be great thanks.

    Use the law of cosines

    To find the distance from where it started to where it ends up.

    Due east is a bearing of 90 degrees.

    180-(90-34)=124.



    To find the bearing back to the point of origin, try using the law of sines.







    That is the bearing heading back to the point of origin.

    Follow all that? The best thing is to outline it and ask questions if you do not understand. Draw a picture. That always heps with these. Get a protractor and a rule and draw it out to scale.
