How did you do it? What rules did you use?
Took me 15mins but i got the inverse of sin(15.6/18) -30 =30.1
2. Does anyone know how many marks the trolley and bars question was because I stupidly rounded up the 3.9 without using any common sense so out 4 bars instead of 3 bars😂🔫 but I got the method correct

I got 20.7 because i did pythagoras and then trigonometry with sin
You were suppose to use TAN since you had the Adjacent and the Opposite, the hypotenuse was for the other triangle above..

It was 4, I suspect you'll get 3 marks anyway though

11. For the trig question did anyone try to do like tan(90) x whatever the other number was and have an error come up on their calculator??

12. How did you gues get 3 for the trolley question???
I got that the cross sectional area was 76cm^2, then I multiplied it 120 to get the volume. Got 9120.
So 8= mass/9120
Did 8 x 9120 then got some long ass answer and then divided by max. trolley weight limit and got near 0😂 Where did I go wrong?
13. I can't remember, but I used the upper bound of v and the lower of u

are you sure you calculated the return journey from work each day too??
Yeah I'm sure I did. It was 36 miles both ways so 180 miles in total

16. How the actual flip do you do the last question? I could substitute the formula in then the calculator wouldn't listen to me 😩😩😩. Then ran out of time...

I think you forgot to convert from g to kg
