Ima Hyker is camped out in the forest. After breakfast she walks 16 km on a bearing

of 327° then she walks 12 km on a bearing of 237°. What bearing will Ima have to

walk to head straight back to her camp? (nearest degree)

I know how to work it mathematically, but I need a good visual representation ! Could any of you do me a favor and graph it to show me to you can graphically look at this?

Hi infinitebrain;

I know nothing about bearings. I get lost going around the corner. I navigate by taking a big ball of twine with me and letting it out as I go. Then I follow it back. I do not use bread crumbs because wasting food is wrong.

Here is what I drew:

hi infinitebrain,

To avoid confusion amongst navigators, and so that they can use a magnetic compass to determine which way to go, bearings are measured **clockwise from North.**

I have made a sketch of the problem. The distances and angles are not accurately shown.
