For the trigonometry question with the triangle split into two, and you had to find x? What was it? I got like 30 decimal, think its wrong

I messed that up I used cosine to find angle of top triangle then was gonna minus it from 180 but it gave me like 126 then I minused from 180 and it was like 52 I tried soh cah Toa and i got a minus... just couldn't do it

The last answer was about 80.4 - angle B was 40 degrees but the question asked for angle A. It was part of the working out though so you might get a few marks for that.

That's good; I'd be happy with that. I was unfortunately running out of time by that question.

I got fed up with the huge 5 mark questions so actually started working from the back lol

I worked out angle C and angle B, but didn't RTFQ (read the full question), so I think we would have got 4? 2 marks per angle, I'm not sure.
