If the bearing of A from B is 150, find the bearing of B from A.
The bearing of B from A is 330 degrees, which is the opposite direction from 150 degrees.
To understand this, imagine standing at point A and looking towards point B. If B is at a bearing of 150 degrees from A, it means that B is 150 degrees to your right. Now, if you turn around and face the opposite direction (180 degrees), and then continue turning to your right for another 150 degrees, you will be facing the direction of B from A, which is 330 degrees.
To find the bearing of B from A, you can use the fact that the bearing of A from B plus the bearing of B from A must add up to 360 degrees.
Given that the bearing of A from B is 150 degrees:
Let the bearing of B from A be x degrees.
Thus, we can write the equation:
150 + x = 360
To solve for x, subtract 150 from both sides of the equation:
x = 360 - 150
x = 210
Therefore, the bearing of B from A is 210 degrees.
