without a specific question it is hard to help.
In Q1 here, you will make progress if you can close your eyes and picture yourself standing at A facing North. What angle do you have to turn through in a clockwise direction to be able to face B?
The answer is 180 + 40 = 220. The bearing is therefore 220.
At foundation I think the only other issue maybe reversing a bearing. (in this case what is the bearing of A from B).
My rule for this is to reverse a bearing add 180. If the answer is greater than 360 then take 360 off.
In this case 220+180=400. 400 is bigger than 360 so take 360 off which gives 40. In other words if you stand at B and turn through 40 degrees clockwise you will face A.
The 40 in the diagram is the same as the bearing of A from B because of parallel line rules. (Adjacent angles [angles in a "Z"] are equal).
