ok how do i find the area in the first place??

dont need to find the area bro.... Find the lengths of any 1 side of each triangle n den i'll show u how to do... See if u founded CE and BF as they r similar in the triangle CGE and FGB so write like this :
(CE/BF)^2 = A. Of CGE/ A. Of FGB
as CE and BF are lengths so they are in cm n area should be in cm square so v square both sides... ( itx a formula ) hope u r clear now

please tell me that if add-maths for o'level useful anyway ???

AS level math (and to some small extent, A level math) will become a cakewalk if you take it.

ADD MATHS

4sin4x +5 = 7 cos^2 x

I have done this much solution:
4sin4x +5 = 7(1 - sin^2 x)
4sin4x +5 = 7-7sin^2 x
4sin 4x + 5 + 7 sin^2 x - 7 = 0
4sin 4x + 7 sin^2 x + 2 = 0.
Now what?

Hello im here with a new problem its from http://www.xtremepapers.com/CIE/Cambridge O Levels/4024 - Mathematics/4024_s08_qp_2.pdf M/J/08 P2 question 10) E) i) 2X^2-20X+96=2(X-5)^2+K my problem is what is the value of X here and how do i find K??

ADD MATHS

4sin4x +5 = 7 cos^2 x

Are you sure that's the question. Because i don't think we're gonna land anywhere near a solution.

 

[zeshan huq]

never mind i solved it thanks by the way

[leosco1995]

To find the value of K, expand the right hand side and compare the co-efficients. 96 = 50 + K, hence K = 46.

can anyone tell me what does this means" a point is lying in the same vertical plane as two other points p and q on the horizantal ground"

p and q are on x axis . and the point lies on the y axis.
