the arrangement of the question parts actually gives you the clue on how to solve for x.
for (i) & (ii), you already have your angles BAD & BCD (the working you scribbled is correct)
for (iii), angles BAD and BCD are angles in the opposite segments (which means that they add up to 180), so you can put (i) & (ii) together to solve for x.
(answer: x=64)
for (iv), substitute answer from (iii) into (i) to get angle BAD, then can get angle PAD.
