Angles of elevation and depression (article) Khan Academy
The bearings tell me the angles from "due north", in a clockwise direction. Since 130 40 = 90, these two bearings will give me a right triangle. From the times and rates, I can find the Since 130 40 = 90, these two bearings will give me a right triangle....

Calculating Bearings Recall: All bearings are measured clockwise, from north, and are written as 3 digits, eg 013 °. To find the bearing of B from A, draw a line from A to B, draw how to draw a beacon Many everyday problems in trigonometry involve such terms as bearings, angles of elevation, and angles of depression. 060 and ship B 56 km from port at a bearing of 115. We therefore draw another diagram with the east line drawn in, and construct two right-angled triangles to find how far north and east of port the two ships are. (Verify the angles of 30° and 25° in the diagram !) Ship A
