Corrections:
Question 9: I found x and y, but omitted the final part of this question, finding the length and width of the rectangle. Length = 5(4.5)-(-0.5)-8=15 and Width = 3(4.5)+(-0.5)-4 = 9. Make sure you always re-read the question, to make sure you have fully answered it!

Thank you very much! I've got my first maths GCSE tomorrow so this has been very helpful :)

[ToonOfLancing]

Ref Q8: In my school days we learned Heron's Rule for the area of a triangle and found it simpler that the trigonometric methods. Is this still a valid method for solving such problems?

[ImranKhan-kzqo]

for question 9 (48:00) do you not need to workout the length n width by subbing back into the expressions on the diagram ?

[silverarrow]

Can the sine rule also be used for question 8?

[doubletrouble]

1:27:20 could you please tell me what topic is question 20?

[GC_balls]

what program do you use for the calculator and for drawing?

[jayladhar]

For q18, how would I know what rules to use in the exam

[Smosas]

My g thank you helped me a lot if I did good tomorrow I promise I’m gonna give you £4.99😭🫶🏼
