Original post by Burkay

I got 40 for the angle

thank jesus - how did you find the rest of the paper?

i think i did really well but then again i say that all the time and **** up so...

For the last question there seems to be a split between 80.4, 80.1 or 40?

The paper was really easy, just a few silly answers I got so I counted about 92 marks

I got 40 for the bottom left angle, 5 FOR THE RIGHT Length AND 81.8 FOR THE ANGLE OF X

I need an actual completed paper to use as a mark scheme, although this does help I feel as though I forgot some of my answers

This markscheme is really accurate

For question 17 did you guys use tan-1

I put 80.4. Not sure about 80.1, but 40 just isn't right

I got 3-x/(x-3)(3x+4) because I didn't think that it could be simplified?!?

Same here😢

Phew!

I think this answer is wrong also as when you factorise the denominator, you get (3x+4) (x-3) and the numerator was 3-x . 3-x and x-3 are not the same thing. Therefore, you can't cancel out.

It does cancel down though because 3x^2 -5x-12 also factorises to (3-x)(-4-3x) which then cancels out.

For question 7 it was 3.7 wasn't it? It was closer than the 3.8 value

Yeah I'm sure it was, i think the person made mistake.

I literally subbed it in and it is right!!!

Guys, y'know for the one with the mean? I did everything and got 7.92 and it's there in my exam paper, but then it said estimate, so I rounded it to 8. How many marks do I lose?

Did you use the area formula, then cosine and then either cosine again or sine?

probably only 1

1/2 x 7 x 8 x sin(c) = 18
18/(1/2x7x8) =sin (c)

sin*-1 0.6(or whatever)

= 40.01

then i subbed it in:
1/2 x 7 x 8 x 40.01 = 18
