    Does anyone remember their answer for...22, I think? Making y the subject?

    I forgot what the numbers were but I think I got (5b - x)² = y. Not sure whether that's even near the realm of correct but rearranging questions are always hit-and-miss for me.
    I got 5b^2-x im not sure though yours is probably right though

    99 - B
    125 - A
    And 150 something for an A*

    Guys for the trigonometry and Pythagoras question with triangles where you must find the missing angle the answer was 30.1° but I misread and got 30° as the answer. What's the max number of marks I could get?? I think I did everything else right...I used tan^-1 and then divided the side lengths I hope that's right????

    I put brackets around the whole thing so it didn't imply that I was only squaring the x on the left side and not the whole equation.

    I'm not too sure, if it was 2 marker I imagine you'll get at least 1 mark though.

    whoever created this needs to hurry up, and also question 25 is 80.1, period
    no its 80.4 but theyll accept 80.1 i think. It depends whether or not you used precise values, by storing in calculator
