I cant get to the answer !

you have the area of both the shapes??

 

[Mayedah]

you have the area of both the shapes??

How will we find the area of both the shapes ? We jst have the length ratio of PU :UV ?

http://www.xtremepapers.com/papers/...matics - Additional (4037)/4037_s11_qp_21.pdf i can't find the correct second value of z in question 10 part iii it's about trigonometry
http://www.xtremepapers.com/papers/...ematics - Additional (4037)/4037_s09_qp_2.pdf and the question 11 b part
please

i also couldn't draw the correct vector diagram for this question

 

[scouserlfc]

First find the relative velocity im pretty sure u guys know that
use the equation
V(L/S) = V(L) + (-V(S))
then use a scale of possibly 1 cm = 5km/h and plot a relative velocity line at a bearing of 270* which should if i remember it correctly about 9 cm then make an arrow showing that its moving towards the left !
Now connect the -V(s) line towards the left end of the relative velocity line u made before in such a way that u make 150* so the angle between the relative line and this new line is 60* now this line should be of 3 cm !
Last just join the remaining line to the figure and u got the diagram now use cosine rule for first part then sine rule and a bit of bearing knowledge in second part that all
