lol for the angle of elevation i had zero degrees coz my calculator was on radians, but i realised and changed it. it had me stumped for a fuking while but i had plenty of time at the end
. Haha for that one i think i got like 8 or 7 degrees in the beginning but then realised you had to round it up and did so. By the way, i mentally LOL'd so hard at your picture ;D

For the non-calculator part, the one where you had to draw the triangle at 90 degrees anti-clockwise about O. Did you just draw the triangle with one of the corners at point O? I wasn't 100% sure what it meant by about point O.
I made my point A 2 squares above point O. Basically O was the centre and you rotated the triangle around.

Okay, I did a different triangle .. I'll draw it up now ..

It's the one on the right rotated around point O.

Yeah it was 17 degrees,
the ratio was 3:10

Looking at the incoming posts made me realise how much questions I screwed up in multiple choice and the first section!
I HOPE for 90+ RAW!

This forum is really depressing me :( I am realising how many stupid errors I have made... like Q20 - I worked out the answer to be -7 and I remember my working and everything but for some reason I wrote -15...
