Good evening Irah! Here are my workings for this question.

An alternative approach for part i is to

1. Find angle AQB (same as what I wrote on paper), followed by angle ABQ (since triangle ABQ is isosceles)

2. Find angle ABC in triangle ABC since the other two angles are already given

3. Sum ABQ and QBC to obtain QBC

Let me know if you need more help and I will do my best to explain them again!
