THIS QUESTION WAS STUPID, IT'S SO UNCLEAR. They never said the kite in part b is the same as the kite in part a
7. How about the scale one?
I wrote 1:0.625
i dont know which one should be n

8. I think it was 1:160 or sth like that.. Cause u have to convert the unites of 80 metres to 8000 centimeters..

What did u get for the last question?
13. I forgot the exact ans i wrote
But at the start i turn T as the subject
And turn A as the subject
Then substitute these things into the equation

14. I guess you just need to substitute T.

16. Did you guys get 10.5 and 0.5 for x or something for the second last question?
17. Yeah i got that
18. If you can remind me of the two equations I'll do it on a paper and attach a picture on the thread..
19. How about the first question?
What is the relationship between shape T and S?
