Question 1 Report

The bearing of P from Q is x, where 270o < x < 360o. Find the bearing of Q from P
Answer Details
The bearing of P from Q is the angle measured clockwise from the north direction to the line PQ. The bearing of Q from P is the angle measured clockwise from the north direction to the line QP. Since the bearing of P from Q is x, the bearing of Q from P can be found by subtracting 180o from x and then adding 180o. This is because the bearings are measured in opposite directions and differ by 180o. Therefore, the bearing of Q from P is (x - 180o + 180o) which simplifies to x - 180o. Thus, the answer is (x - 180)o.
