question 5 a part (i)
View attachment 19225
this question is only worth 2 marks and so was sondering if anyone had a quick/easier method of doing this... for my solution i thought it was to much working for 2 marks.
this is what i did
first pythag
then trig(right angle)
then cosine rule (non right angle)
then sine rule (non right angle)
then double angle formulae
then division of equations
i dnt have solutions so i can't see how they do it
my working goes for a page
any help is apreciated
