Drew a line from one of the corners to the radius to create an isosceles triangle including the origin and the angle of 48. Therefore the other angle was 48 (isosceles triangle), so the angle at the origin was 84 (180-96).

This meant that the angle at the other point (hard to explain without a diagram) was 42 because the angle at the circumference is half that at the origin.

As this was a big large isosceles triangle (already marked), the other two angles were 180-42/2 = 69.

Then alternate segment theorem meant the angle that needed to be found = 69.

yeah you split the shape into two chords with it

Q22 was 78 not 69

No it's definitely 69, that's even what the moderator wrote on the unofficial mark scheme he's creating and loads of other people got the same answer
at a tangent, angle is 90
we're given 48
90-48 = 42
alternate segment theorem
means the angle in the isosceles triangle is also 42
Angles in a triangle add up to 180°, base angles in an isosceles are equal.
(180° - 42°) ÷ 2 = 69°

Hey, if anybody is willing to contribute the answers, and preferably the questions, then I shall set up a mark scheme for you all. Thanks in advance!

Can people please attach question numbers to their answers? Method would be appreciated.

Spoiler

There was a box plox question which stated "how many 16 year olds earn 130 pounds or move a week. The answer was 150.

Katie has 3 varnish jars. Each jar holds 2.5 litres of varnish. Katie wants to cover the whole area, does she have enough jars?
For every 5m², katie uses 1litre of varnish.

Answer: (2.5x2X2)+(4x10)=50
50/5=10litres needed, so katie doesnt have enough

Thanks

For the fill in the table question, when y was inversely proportional to x, I got k = 100
?? Anyone else?
Can't remember what I worked out for the table though.

yeah K was 100 and answers were 100, 1 25 or 4 or something like that

There are people on this forum who have not yet sat this exam. Some may be asking to confirm questions and answers only to get the questions and answers for when they sit it later today.The grades will rise if you give answers on here. Do not jeopardise your grade by giving answers until tomorrow.
