    i think trapezium !! yeah loads of people were saying arrowhead but it couldn't be that
    Yes, an arrowhead has a reflex angle and x=30... That's how I ruled it out but I was still unsure.

    What was the other option that I said I might have picked? I am worried I picked the wrong one.
    You said D or E. E was trapezium, I THINK D was rhombus but don't quote me on that.

    Can someone explain to me how the escalator question was 36? It took her 90 seconds to walk up it and 60 seconds standing still. I got 45 seconds.
    let the distance be d.
    let the speed of the escalator be x and the speed of her walking be y.
    60 = d/x
    90 = d/y
    rearrange them to get
    60x = d
    90y = d
    60x = 90y
    x = 90y/60 = 3y/2
    the speed when she is walking up a working escalator = x+y = (3y/2) + y = 5y/2
    so the time is = d/(5y/2) = 2d/5y = (2/5)(d/y) = (2/5)(90) = 36
