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

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.
