If the bearing of Q from P is 145 find the bearing of Q from P
it's 180° different.
Recall that bearings are in the range 0-360°
PQ = 145o
QP = 145+180 = 325o.
To find the bearing of Q from P, we need to determine the angle between the line connecting P and Q and the reference direction, usually the north direction.
Given that the bearing of Q from P is 145, we can assume that it is measured clockwise from the north direction.
To visualize this, imagine a compass with a reference direction of North. Start by pointing your compass needle towards the North direction. Then, rotate the compass clockwise by 145 degrees. This will give you the direction of Q from P.
Alternatively, if you prefer to use math, you can calculate the bearing using the following formula:
Bearing = 360 - Angle
In this case, the bearing of Q from P would be:
Bearing = 360 - 145 = 215
Therefore, the bearing of Q from P is 215 degrees.
