Help with Trigonometric Bearings

[BAL]

I am trying to solve these questions and, although I have solutions, they do not say how they are solved:

Although I have solved Parts A and E, I am unsure as to how to go about Parts B, C and D.

This is my working out. For part B, I am unsure as to why I'm wrong at all. For Part C, I have no idea how to go about it, especially that Part B is wrong. For Part D, although I worked out the angle x to be 46.11°, I have no idea how to apply that to my bearing.

Thank you.

For (b), you accidentally answered (e). It doesn't ask how far it is from the start, but how far east it has flown. They want one component of the resultant, not its length!

Part (c) asks for the other component.
