from where did you get 2y in '-x+2y=18'WOW ur Questions are soo long....... for this one .... just form equations and replace them in different equations its very easy but concentrate!

Looks like you understand more than i dobut i perfectly got what u said ! i do it this way too but that one is easier and looks more sophisticated,,
y+z=18from where did you get 2y in '-x+2y=18'
thank youy+z=18
and z=x+y
so place x+y instead of z
x+y+y=18
x+2y=18
and sorry there is no -with x
if u check in the previous pages iv posted a pic i guess after pgI need help PLEASE
http://papers.xtremepapers.com/CIE/Cambridge IGCSE/Mathematics (0580)/0580_w12_qp_41.pdf
Question 1(d)(ii) Can you show me the steps? I have Maths paper 4 tomorrow so please anyone ans quickly. Thnks
sorry its page 167 only just check in the endi
if u check in the previous pages iv posted a pic i guess after pg
167
tell me if u found it or else ill post it againsorry its page 167 only just check in the end
B) i) cyclic ii) since tc and bo are parallel, alt. interior angles are equal so x = 40 . OA and OB are both radii so AOB is an isosceles triangle. Both base angles are equal and so 130 + 2y = 180 , y = 25 . Angle Z is supplementary to x + y becuase they are on a cyclic quadrilateral so, 180 - 25 - 40 = z , z = 115.
Thank you very muchthis is the answer of oct nov 2012 p2 q no 1 dii
tnx u...2/5 x 1/4. thats easy
This is part A) I asked B) , thanks anywaysB) i) cyclic ii) since tc and bo are parallel, alt. interior angles are equal so x = 40 . OA and OB are both radii so AOB is an isosceles triangle. Both base angles are equal and so 130 + 2y = 180 , y = 25 . Angle Z is supplementary to x + y becuase they are on a cyclic quadrilateral so, 180 - 25 - 40 = z , z = 115.
iii) angle oct is equal to 90 because angle between radius and a tangent is always 90.
iv) angle Aoc = 2 x z because they are on the same segment so Aoc = 230.
I calculated mine and just had one mistake so i will lose only one marki made a really stupid mistae but i guess in sha Allah it will be above 64
