    Everyone I spoke to got 69
    i got 69 in the exam and it looks like it is 69, i used alternate segment twice, first one giving me the top angle on the isosceles then taking it away from 180 then dividing by 2 to give me base angle and then the 2nd time gave me the angle.

    it was like (0.35) + (0.05 x 0.35) + (0.05 x 0.05 x 0.35)

    which is = 0.35 + 0.017 + 0.000875

    = 0.367875

    thats correct but then you need to factorise it to 3a(2+a) because anything times by three is always a multiple of three
