Yeah, I was confused whether it was saying that her parents would pay for everything or whether they were not well payed which in this case is (ii) --that's what I put :/ and the last page was not too bad.... but overall it wasn't as hard as last year's

They were going to help pay. What you put is right, as their small earnings were mentioned. :smile:

What did people get for the one where you cross four boxes? (In French listening)

I have a sneaking suspicion that there will be a constructions question on Maths today. There hasn't been one for the past two years!

(If anyone needs some revision for this, BBC has a good animated thingy http://www.bbc.co.uk/schools/gcsebitesize/maths/geometry/locirev2.shtml)

How are we feeling about maths tomorrow?

Not bad, just hope it stays like the May 2012, hope it doesnt get soo hard. Does anyone have a site for the HARDEST ever maths questions? do you practice Spec. B papers?

-maths
-english
-french
-chemistry
-biology
-physics
-futhur pure mathematics
-ICT

PM me if you wanna join the group and discuss about the papers. :smile:

pls note that even these will be moderated by the student rooms (if im not mistaken)
and will only be discussing the most probable questions
(and other things...)

hey im doing chem bio physics.. :biggrin:

i want to join too!!!

Just remember that triangles AOD, DOC, and COE are isosceles triangles.
Now everything is easy! Lets Assume angle DCO = y

So,
y=2x (Exterior angle of a triangle is equal to the sum of the two opposite angles)
Now we look at triangle DOC. We can take Angle DOC as y as well. (Isosceles triangle so two angles are equal)
Now we can form another equation.
y=69-x
Now equate the two equations,
so 69-x=2x
3x=69
x= 23.

This is just one way of solving the sum, but there are so many other methods, such as solving by finding angles DAO (which is 55.5).

Hope this helped, and Good Luck for today's Paper !
I hope its not very tough.

Pls explain the way of solving it via finding 55.5 as DAO

Yeah I got exactly the same! A lot of people crossed the 3 month one I think, so I'm not sure if we got all right, hope so though!

It's not 3 months one because they said he found his job monotonous at 3 months then after 1 month he left the job.. So that's 4 months not 3

Well actually you can't do much with that 55.5. This method is way more longer and confusing but as you asked it ill show it.

We anyways need y as DCO. And y=2x.
This also means now ODC is also = 2x.

Now this is where things get confusing. Ill put in the best way i can.
We want angle DOC,
we can put this as 180-(69+x)
it is also 180-4x when you look at it from the other Point of View,
Now we write this for the supplementary angle's view.
69+180-x+4x= 180
so we come back to the original equation now, 69=3x, so
x=23.
