Could you elaborate more?Hint: Use similar triangles (right angled triangles).

Thank you so much. I just have one more question. In the examiner report they say another method is to find the average of 25 and 35 as the width of the water. Can you explain what is the mathematical basis for using this method? I cant find it in any textbooks or on the internet?

For rotating an image by 90 degrees the direction must be specified to avoid ambiguity otherwise the marking scheme must allow for both directions. I dont know about 0607 Mathematics but in IGCSE 0580 a direction is always specified for 90 degree rotations so I would assume this to be true for other syllabuses as well.Ok guys, I'm taking the International Mathematics (code 0607) and I'm a little stuck on rotating images. For example, if the question asks us to "Rotate point A by 90 degrees" does that mean 90 degrees clockwise or counter clockwise? (normally the question specifies this but I would like to know JUST in case). Thanks in advance!
It is very difficult to answer the question without knowing which aspect of the question u find difficult? It probably looks like homework and you should try it on your own. But I will give you some tips.Heyya guys!! Could u help me with questiom no. 22, 27 and 28 in the image.
Thanks for getting back to me........nope its not homework, i am a private candidate having my exams in 2 weeks.It is very difficult to answer the question without knowing which aspect of the question u find difficult? It probably looks like homework and you should try it on your own. But I will give you some tips.
Q.22 find the gradient and then use y=mx+c and find the value of c
Q.27 and 28 You need to setup simultaneous equations in terms of a and b using the coordinates given
The methods may differ depending on your syllabus but this is how I would approach it.

OMG!!! I hate working with X now...Which syllabus are you following. I am mostly familiar with 0580 IGCSE mathematics.
PS
In questions 27 and 28, notice that they have given a set of coordinates where x is 0 like (0,5). Use this set of coordinates to find the value of c (which is equal to 5 in both q.27 and 1.28). From there you can easily setup simultaneous equations with remaining set of coordinates. Let me know if you need more help.
a) sin(45) - cos(45)= 0
