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
how about the drawing questikn?

I wrote translation (4 -6 )

not sureee:frown:
