    trigonometry and bearings
    Can you please tell me what does it mean when it says:-
    'The difficulty with trigonometric problems involving bearings is dealing with those angles greater than 90 degrees whose trigonometric ratios have negative values. To avoid this we have to find a right- angled triangle that we can readily use.'
    How do you find a right angle triangle, the book has given me an example but I'm very confused.
