Like AY for Add Maths....???
actually we are not allowed to solve questions by accurate drawing!
i m sorry for that n i do agree that drawing vector diagrams make it easy but the diagram it self is difficult to draw i mean if you give me the diagram i can find out the other stuffU didnt get what i was saying i said make an accurate vector diagram and then use the trigonometry functions to get the answer by making an accurate diagram u will get to know whether the triangle forming is right angled or not and then u can solve,by making a diagram confusions are removed as it shows exactly whats going to happen and it barely takes two to 3 minutes !
Captain can You help me in a question .Will really appreciateRe: O'level Maths, Addmaths and Statistics help available he
Thank you!

Q/Express 81 grams as a percentage of 3kg
81 grams
3kg=3000 grams
this is unitary method
if 3000 g------------100%
then 81 g--------------- x
cross multiply and u would get ans=2.7%
Q) A Farmer needs to fence off a region ABCDEF of his land as shown in figure. He uses a straight wall af,as one of the region.the remaining five sides AB,BC,CD and EF are made from wooden fencing,where AB=EF=X meters and BC=DE=5 meter. The sides AB and EF are right angles to the wall.the total lenght of wooden fencing is 80 meter
i) find CD in terms of x (3)
ii)show that y=292+68x-2x^2 (3)
View attachment 5784
oh sorry i missed one line which is" the total area of the region ABCDEF is Y meter^2"first part :--
80=2x+10+CD
70-2x=CD
I can solve the first part with what u gave but what is y i think u missed something out here see again and then tell ill be waiting !
