The bearing of B from A is 120 degrees. What is the bearing of A from B?
Click For Summary
The bearing of B from A is 120 degrees, which indicates the direction from point A to point B. To find the bearing of A from B, one must subtract 180 degrees from the bearing of B from A. This calculation results in a bearing of 300 degrees for A from B. The discussion emphasizes the importance of understanding directional bearings in navigation. Accurate bearings are crucial for effective route planning and orientation.
For the sake of argument, lets assume this is, in fact, a right triangle with a rectangle inscribed in it.
Here is what looks like a very elegant solution:
Triangles A and B are similar
a/4=2/b
ab=8
But what is happening in that second line? Is there a property of similar triangles I'm forgetting?
