Couple of things you could do for part i.

Triangle of forces - note the line of action of three forces in equilibrium goes through a common point.

Or.
Resolve vertically to get the vertical component at A.
Take moments about B to get the horizontal component at A.
Use Pythagoras to combine and get the magnitude.
