I wrote the answers to all my questions on the exam so i could take them out and my teacher could mark them. some of them I got wrong, my teacher said I got about 95/100 so I tried to remember the actual answers to the ones I got wrong.
I only wrote the final answers, not the working out. Also, I haven't included the drawings and graphs.
EDIT: There are mistakes here, will fix them soon.

Q24.

ii] 8/72
iii] 5
C)i] 55 degrees
ii] 13km
iii] I made a mistake in "Cii" by putting down 14km instead of 13km so I got 249 degrees for this question. I think my teacher got 230 or something, but I can't remember sorry.
Q25.
