Step-by-step explanation:
Given;
We are given that the bearing of point L from point Q is 90 degrees.
Required;
We are required to find the bearing of point Q from point L.
Step-by-step solution;
The bearing of a point is the number of degrees in the angle, measured in a clockwise direction from the north line.
This means we can sketch the bearing of L "from" Q (at 90 degrees) as shown below;
Note that measuring from Q, L is at a 90 degree angle and to the right of Q.
However, measuring from L, we can see that Q would be located at a 270 degree angle (measured in clockwise direction) from the point L.
Therefore,
ANSWER:
The bearing of Q from L is 270 degrees.
