Answer is B by the way.

Is it.. i keep getting D >.>"

 

[jesskies]

Most of these questions are from the 2004 paper right?
This paper has no trigonometry.. Will there be trig in ours?

 

[zavier]

the answer is c.

Answer is a
David - 7.67*8 = 61.36
John - 6.97*8 = 55.76 + 5.60 = 61.36

There will be trig. Basic trig. Sometimes you'll be lucky and one topic will be missed, but most the time they put trig in.

how did u do it but?

 

[zavier]

trial and error...
But I think you can do simultaneous equations. Give me a minute to think about it. Meantime:

(i) Work out the length of CD

Ratio is 1:3 and it tells you that BE is 4cm.
So CD = 4 x 3 = 12cm?

I'm not game enough to try the next. I fail.
